BACKGROUND OF THE INVENTION

This invention relates to the field of information networks, and morespecifically to techniques of developing, providing, and sharing contentin a social networking community, especially one which provides animmersive, collaborative environment for learning.

The Internet and the World Wide Web (WWW) and have brought aboutsignificant changes in how information is exchanged. The Internet hasbeen referred to as the “information superhighway” and has facilitatedrapid dissemination of information to large numbers of people in theUnited States and around the world. Through the Web, users can moreeasily “publish” or otherwise make available to others many differentkinds of information and content, such as through hyperlinked pages.This information includes, naming a few examples, newspaper articles,scientific papers, literary texts, business articles, socialcommentaries, political commentaries, and entertainment columns.

The Internet continues to evolve and advance. The Web facilitates morethan just people retrieving information from institutional sources.Information is being democratized through new sources and ways ofpresenting information such as weblogs or blogs, wikis, podcasts,forums, and on-line social communities. The result is a more sociallyconnected community where people are able to publish, add, and editcontent.

Through the Internet, people want to find and connect with others whoshare similar interests and activities. They want to learn what othersknow. They want to teach what they know. Therefore, there is a need fornew and improved techniques for developing, providing, and sharingcontent, especially to support a vibrant social networking community.

BRIEF SUMMARY OF THE INVENTION

A network-accessible toolbox permits collaborative annotation,facilitating interaction and communication among users. In animplementation, content on a Web page, or other page or documentaccessible through a network or the Internet, can be annotated. A usercan view the page and with the toolbox, select content on the page andmake an annotation or suggestion. Multiple users can view and makeannotations to the same page at the same time. After annotations aremade, users can view the page with annotations made by other users. Theauthor or owner of the page can accept or reject the annotations orsuggestions made to the page. If the owner accepts a particularsuggestion, the selected content is replaced with the suggestion.

Content on a Web page or other network-accessible page can be annotated.In a specific implementation, a Web-based toolbox or othernetwork-accessible toolbox includes a tool for selecting a portion ofcontent on the page and making a suggestion to the selected content.Other users can view the suggestion, the selected content, and thecontent. The content author or provider can accept or reject thesuggestion. If the suggestion is accepted the selected content isreplaced with the suggestion. In an implementation, the suggestions arestored in a separate location from the page (e.g., separate file orseparate database).

In a specific implementation, the system includes a toolbox program orapplication that aids in on-line English education. The toolbox includesa suggestion tool (e.g., option or application). The suggestion tool maybe used, for example, to suggest spelling, grammar, or punctuation editson any typewritten text on any Web page such as Web pages onEnglishCafe.com.

That is, specific aspects of the invention are implemented at a Web siteknown as EnglishCafe. EnglishCafe serves a community focused on Englishlearning. EnglishCafe may be associated with an e-learning site (e.g.,GlobalEnglish) that has on-line courses for teaching students English.Each student at the e-learning site may be given the opportunity to jointhe EnglishCafe community site, where each student can create their ownpages for others to view. Community members need not necessarily beteachers or users associated with the e-learning site.

If a suggestion is received by a blog owner, the blog owner may eitherapprove the suggestion or discard the suggestion. The suggestion may besubmitted by simply selecting the text that the user feels can beimproved. Examples of users who may access one or more options of thetoolbox program include EnglishCafe users, authenticated EnglishCafeusers and anonymous users.

In a specific implementation, the toolbox is used to give a correctivesuggestion to a blog post. The toolbox is user-friendly and easilyaccessible for all the users.

In this specific implementation, toolbox is accessed through theEnglishCafe.com website. When an EnglishCafe user logs into the Website, the user is connected to the EnglishCafe server. When the toolboxis accessed, whatever data entered is saved in the database server andis retrieved from it. These data will be reflected in “suggestion given”and “suggestion received” sections of the blog or Web site. In thisspecific implementation, the toolbox is not a stand-alone single usersystem component. That is, any EnglishCafe user can make a suggestion,but only the blog owner can approve, agree, or discard the suggestion.

The various services provided to the users for the toolbox are based onthe user type. In an implementation, the toolbox includes fivecomponents. The five components include make a suggestion, translate it,hear it, copy, and quote.

Authenticated users can avail all the above services provided by thetoolbox. The anonymous users can only avail the services of “translateit,” “hear it,” and “copy” the text of the blog post.

More specifically, the make a suggestion component is used to give asuggestion to the blog owner an alternative way that they could haveexpressed themselves. The translate it component is used to translate aparticular text of the blog to the desired language of the user. Thereare some pre-populated languages that have been set in the toolbox whichcan be used to translate. The hear it component is used to hear aparticular text of the blog in the desired voice that has been selected.The copy component is used to copy a particular text of the blog and useit for reference. The quote component is used to comment on a particulartext of the blog instead of the normal comment to the entire blog.

In an implementation, comments made using the suggestion tool canreplace the text that is selected, after approval by the blog writer.Such an approach is not simply for commenting but also for suggestingand correcting. The tool allows for an explanation of suggestion. Thetool allows for multiple suggestions on the same text. In a furtherimplementation, the tool allows not only suggestions, but additionally atranslate it feature, hear it feature, copy it feature, and quote itfeature, in any combination.

In a specific implementation, a method of annotating a document includesallowing a first user to access the document. The document accessed bythe first user includes content provided by a second user and embeddedexecutable code. Using executable code of the document, detecting anindication by the first user of a first selection of text in thecontent. After the detecting the indication by the first user, using theexecutable code, seeking a first suggestion input from the first user.Storing the first suggestion input from the first user. After thestoring the first suggestion input from the first user, showing thesecond user the first suggestion input from the first user. Presentingthe second user a first option to accept the first suggestion input anda second option to reject the first suggestion input. When the seconduser accepts the first suggestion input, making a replacement of thefirst selection of text in the content, provided by the second user, ofthe document with the first suggestion input.

In an implementation, when the second user rejects the first suggestioninput, the method includes not making a replacement of the firstselection of text in the content, provided by the second user, of thedocument with the first suggestion input.

The showing the second user the first suggestion input from the firstuser may include displaying the document and the content provided by thesecond user to the second user. Displaying a toolbox dialog boxincluding a first box and a second box, where the first box includes thefirst selection of text, the second box includes the first suggestioninput, and the toolbox dialog box is superimposed over at least aportion of the document.

In an implementation, before the when the second user accepts the firstsuggestion input, making a replacement of the first selection of text,the method includes allowing a third user to access the document. Usingexecutable code of the document, detecting an indication by the thirduser of a second selection of text in the content, where the secondselection of text includes at least a portion of the first selection oftext. After the detecting the indication by the third user, using theexecutable code, seeking a second suggestion input from the third user.Storing the second suggestion input from the third user. After thestoring the second suggestion input from the third user, showing thesecond user the second suggestion input from the third user. Presentingthe second user a third option to accept the second suggestion input anda fourth option to reject the second suggestion input. When the seconduser accepts the second suggestion input, making a replacement of thesecond selection of text in the content, provided by the second user, ofthe document with the second suggestion input. And, after the making areplacement of the second selection of text, not permitting the seconduser to accept the first suggestion input.

In an implementation, after the when the second user accepts the firstsuggestion input, making a replacement of the first selection of text inthe content, provided by the second user, of the document with the firstsuggestion input, the method includes allowing a third user to accessthe document, where the document accessed by the third user includescontent provided by the second user, the accepted first suggestioninput, and embedded executable code. Using executable code of thedocument, detecting an indication by the third user of a secondselection of text in the content, where the second selection of textincludes at least a portion of the accepted first suggestion input.After the detecting the indication by the third user, using theexecutable code, seeking a second suggestion input from the third user.Storing the second suggestion input from the third user. After thestoring the second suggestion input from the third user, showing thesecond user the second suggestion input from the third user. Presentingthe second user a third option to accept the second suggestion input anda fourth option to reject the second suggestion input. And when thesecond user accepts the second suggestion input, making a replacement ofthe second selection of text in the content, including the at least aportion of the accepted first suggestion input, with the secondsuggestion input.

The method may further include seeking an explanation of the firstsuggestion input from the first user, storing the explanation, andduring the presenting the second user a first option to accept the firstsuggestion input and a second option to reject the first suggestioninput, presenting the second user the explanation.

Before the making a replacement of the first selection of text in thecontent, provided by the second user, the method may include promptingthe second user to confirm the acceptance of the first suggestion input.

The method may further include when the second user accepts the firstsuggestion input, sending a notification to the first user to inform thefirst user that the first suggestion input was accepted.

In a specific implementation, a system includes a server, accessible toa set of client devices via a network. The server stores a set ofdocuments, accessible to each of the client devices via the network.Each document includes embedded executable code, and when the code isdelivered to a client device, invokes a suggestion tool application torun at the client device. The suggestion tool, executing at the clientdevice, detects any selections a first user at the client device makesto first content of a first document delivered to the client device andrequests for each detected selection of a portion of the first content asuggestion from the first user. The first content is provided by asecond user.

There is a suggestions database residing on a storage device, connectedto the server. The suggestions database includes an entry for eachsuggestion made to the first content of the first document, each entryincluding a suggestion field and a position field. The suggestion fieldincludes text of the suggestion and the position field includes aposition of where in the first content the suggestion was made.

There is a user content database residing on the storage device,connected to the server. The user content database includes an entryincluding a content field. The content field includes text of the firstcontent, and when the second user accepts the suggestion, a portion ofthe text of the first content where the suggestion was made, indicatedby the position, is replaced with the suggestion.

Each entry in the suggestions database may include a paragraphidentifier field that references the first content in the user contentdatabase. In an implementation, the position field for each entry in thesuggestions database is a first position field, and each entry in thesuggestions database includes a second position field. The firstposition field indicates a beginning position of a detected selection,and the second position field indicates an ending position of thedetected selection.

In an implementation, the suggestion tool, executing at the clientdevice, requests for each detected selection of a portion of the firstcontent an explanation of the suggestion from the first user. Theexplanation may be stored in the suggestions database. The explanationmay be optional.

In a specific implementation, a method includes receiving firstsuggestion information for a first selected portion of content from afirst client device of a first user. The content is provided by a seconduser. The first suggestion information includes a first suggestion forthe first selected portion of the content for the second user to acceptor reject.

The method includes storing in a suggestion database the firstsuggestion, and first starting and ending positions. The first startingposition indicates a position in the content where the first selectedportion begins, and the first ending position indicates a position inthe content where the first selected portion ends. The first selectedportion is between the first starting and ending positions.

The method further includes receiving an indication that the second userhas accepted the first suggestion, after the receiving an indication,retrieving the first suggestion from the suggestion database, andinserting the retrieved first suggestion into the content at a locationindicated by the first starting and ending positions, whereby the firstselected portion of the content is replaced by the first suggestion.

In a specific implementation, the method further includes receivingsecond suggestion information for a second selected portion of contentfrom a second client device of a third user. The second suggestioninformation includes a second suggestion for the second selected portionof the content for the second user to accept or reject. The methodfurther includes storing in the suggestion database the secondsuggestion, and second starting and ending positions.

The second starting position indicates a position in the content wherethe second selected portion begins, and the second ending positionindicates a position in the content where the second selected portionends, the second selected portion being between the second starting andending positions. The method further includes receiving an indicationthat the second user has accepted the second suggestion, after thereceiving an indication that the second user has accepted the secondsuggestion, retrieving the second suggestion from the suggestiondatabase, and inserting the retrieved second suggestion into the contentat a location indicated by the second starting and ending positions,whereby the second selected portion is replaced by the secondsuggestion. The second selected portion may include at least a portionof the first suggestion.

In a specific implementation, the method further includes before thereceiving an indication that the second user has accepted the firstsuggestion, receiving second suggestion information from a second clientdevice of a third user. The second suggestion information includes asecond suggestion for a second selected portion of the content for thesecond user to accept or reject. At least a portion of the first andsecond selected portions overlap.

The method further includes storing in the suggestion database thesecond suggestion, and after the receiving an indication that the seconduser has accepted the first suggestion, not permitting the second userto accept the second suggestion.

The first starting position may be a first numerical value and thesecond starting position may be a second numerical value, greater thanthe first numerical value.

The content may be stored in a user content database that is separatefrom the suggestion database. The suggestion database may be remote fromthe first client device. The online content may be stored in a usercontent database that is separate from the suggestion database. In animplementation, the toolbox tool is implemented as a cloud-based tool.The suggestions or annotations can be stored separately from the contentitself (e.g., different files). However, the suggestions and content mayreside on the same hard drive, or same folder or directory, or ondifferent hard drivers or in different directories.

Other objects, features, and advantages of the present invention willbecome apparent upon consideration of the following detailed descriptionand the accompanying drawings, in which like reference designationsrepresent like features throughout the figures.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a simplified block diagram of a distributed computer network100 incorporating an embodiment of the present invention. Computernetwork 100 includes a number of client systems 113, 116, and 119, and aserver system 122 coupled to a communication network 124 via a pluralityof communication links 128. Communication network 124 provides amechanism for allowing the various components of distributed network 100to communicate and exchange information with each other.

Communication network 124 may itself be comprised of many interconnectedcomputer systems and communication links. Communication links 128 may behardwire links, optical links, satellite or other wirelesscommunications links, wave propagation links, or any other mechanismsfor communication of information. Various communication protocols may beused to facilitate communication between the various systems shown inFIG. 1. These communication protocols may include TCP/IP, HTTPprotocols, wireless application protocol (WAP), vendor-specificprotocols, customized protocols, and others. While in one embodiment,communication network 124 is the Internet, in other embodiments,communication network 124 may be any suitable communication networkincluding a local area network (LAN), a wide area network (WAN), awireless network, a intranet, a private network, a public network, aswitched network, and combinations of these, and the like.

Distributed computer network 100 in FIG. 1 is merely illustrative of anembodiment incorporating the present invention and does not limit thescope of the invention as recited in the claims. One of ordinary skillin the art would recognize other variations, modifications, andalternatives. For example, more than one server system 122 may beconnected to communication network 124. As another example, a number ofclient systems 113, 116, and 119 may be coupled to communication network124 via an access provider (not shown) or via some other server system.

Client systems 113, 116, and 119 typically request information from aserver system which provides the information. For this reason, serversystems typically have more computing and storage capacity than clientsystems. However, a particular computer system may act as both a clientor a server depending on whether the computer system is requesting orproviding information. Additionally, although aspects of the inventionhas been described using a client-server environment, it should beapparent that the invention may also be embodied in a stand-alonecomputer system.

Server 122 is responsible for receiving information requests from clientsystems 113, 116, and 119, performing processing required to satisfy therequests, and for forwarding the results corresponding to the requestsback to the requesting client system. The processing required to satisfythe request may be performed by server system 122 or may alternativelybe delegated to other servers connected to communication network 124.

According to the teachings of the present invention, client systems 113,116, and 119 enable users to access and query information stored byserver system 122. In a specific embodiment, a “web browser” applicationexecuting on a client system enables users to select, access, retrieve,or query information stored by server system 122. Examples of webbrowsers include the Internet Explorer browser program (e.g., versions6.0 and 7.0) provided by Microsoft Corporation, the Firefox browserprovided by Mozilla, the Safari browser and Mobile Safari browserprovided by Apple Corporation, the Chrome browser provided by Google,the Opera browser provided by Opera Software, and others.

FIG. 2 shows an exemplary client system (or server system) of thepresent invention. In an embodiment, a user interfaces with the systemthrough a computer workstation system, such as shown in FIG. 2. FIG. 2shows a computer system 201 that includes a monitor (e.g., colormonitor) 203, screen 205, cabinet 207, keyboard 209, and mouse 211.Mouse 211 may have one or more buttons such as mouse buttons 213.Cabinet 207 houses familiar computer components, some of which are notshown, such as a processor, memory, mass storage devices 217, and thelike.

Mass storage devices 217 may include mass disk drives, floppy disks,magnetic disks, optical disks, magneto-optical disks, fixed disks, harddisks, CD-ROMs, recordable CDs, DVDs, recordable DVDs (e.g., DVD-R,DVD+R, DVD-RW, DVD+RW, HD-DVD, or Blu-ray Disc), flash and othernonvolatile solid-state storage (e.g., USB flash drive),battery-backed-up volatile memory, tape storage, reader, and othersimilar media, and combinations of these.

A computer-implemented or computer-executable version of the inventionmay be embodied using, stored on, or associated with computer-readablemedium or a computer program product. A computer-readable medium mayinclude any medium that participates in providing instructions to one ormore processors for execution. Such a medium may take many formsincluding, but not limited to, nonvolatile, volatile, and transmissionmedia. Nonvolatile media includes, for example, flash memory, or opticalor magnetic disks. Volatile media includes static or dynamic memory,such as cache memory or RAM (e.g., 128 megabytes). Transmission mediaincludes coaxial cables, copper wire, fiber optic lines, and wiresarranged in a bus. Transmission media can also take the form ofelectromagnetic, radio frequency, acoustic, or light waves, such asthose generated during radio wave and infrared data communications.

For example, a binary, machine-executable version, of the software ofthe present invention may be stored or reside in RAM or cache memory, oron mass storage device 217. The source code of the software of thepresent invention may also be stored or reside on mass storage device217 (e.g., hard disk, magnetic disk, tape, or CD-ROM). As a furtherexample, code of the invention may be transmitted via wires, radiowaves, or through a network such as the Internet.

FIG. 3 shows a system block diagram of computer system 201 used toexecute the software of the present invention. As in FIG. 2, computersystem 201 includes monitor 203, keyboard 209, and mass storage devices217. Computer system 501 further includes subsystems such as centralprocessor 302, system memory 304, input/output (I/O) controller 306,display adapter 308, serial or universal serial bus (USB) port 312,network interface 318, and speaker 320. The invention may also be usedwith computer systems with additional or fewer subsystems. For example,a computer system could include more than one processor 302 (i.e., amultiprocessor system) or a system may include a cache memory.

Arrows such as 322 represent the system bus architecture of computersystem 201. However, these arrows are illustrative of anyinterconnection scheme serving to link the subsystems. For example,speaker 320 could be connected to the other subsystems through a port orhave an internal direct connection to central processor 302. Theprocessor may include multiple processors or a multicore processor,which may permit parallel processing of information. Computer system 201shown in FIG. 2 is but an example of a computer system suitable for usewith the present invention. Other configurations of subsystems suitablefor use with the present invention will be readily apparent to one ofordinary skill in the art.

Computer software products may be written in any of various suitableprogramming languages, such as C, C++, C#, Pascal, Fortran, Perl, Matlab(from MathWorks, www.mathworks.com), SAS, SPSS, JavaScript, AJAX, Java,Adobe Flash, Adobe Shockwave, or Microsoft Silverlight, or combinationsof these. The computer software product may be an independentapplication with data input and data display modules. Alternatively, thecomputer software products may be classes that may be instantiated asdistributed objects. The computer software products may also becomponent software such as Java Beans (from Oracle) or Enterprise JavaBeans (EJB from Oracle).

An operating system for the system may be one of the Microsoft Windows®family of operating systems (e.g., Windows 95, 98, Me, Windows NT,Windows 2000, Windows XP, Windows XP x64 Edition, Windows Vista, Windows7, Windows CE, Windows Mobile), Linux, HP-UX, UNIX, Sun OS, Solaris, MacOS X (e.g., Macintosh), Alpha OS, AIX, IRIX32, or IRIX64. Otheroperating systems may be used. Microsoft Windows is a trademark ofMicrosoft Corporation. The computer may include any number of installeddrivers such as audio drivers.

Furthermore, the computer may be connected to a network and mayinterface to other computers using this network. The network may be anintranet, internet, or the Internet, among others. The network may be awired network (e.g., using copper), telephone network, packet network,an optical network (e.g., using optical fiber), or a wireless network,or any combination of these. For example, data and other information maybe passed between the computer and components (or steps) of a system ofthe invention using a wireless network using a protocol such as Wi-Fi(IEEE standards 802.11, 802.11a, 802.11b, 802.11e, 802.11g, 802.11i, and802.11n, just to name a few examples). For example, signals from acomputer may be transferred, at least in part, wirelessly to componentsor other computers.

In an embodiment, with a web browser executing on a computer workstationsystem, a user accesses a system on the World Wide Web (WWW) through anetwork such as the Internet. The web browser is used to download Webpages or other content in various formats including HTML, XML, text,PDF, and postscript, and may be used to upload information to otherparts of the system. The web browser may use uniform resourceidentifiers (URLs) to identify resources on the web and hypertexttransfer protocol (HTTP) in transferring files on the web. The webbrowser may include any number of various plug-ins such as plug-ins forplaying audio information.

A specific implementation of this invention is a social network forteaching and learning the English language. One of skill in the artwould understand that the principles of the invention apply to teachingand learning other subjects, including languages other than English. Theprinciples of the invention could apply to teaching and learninglanguages such as French, German, Portuguese, Korean, Russian, Turkish,Spanish, Italian, Chinese, Japanese, Arabic, and other languages. Thesystem provides users with a virtual immersion in different languages,cultures, and customs because users can have rich, interactiveexperiences with other users from across the world.

Aspects of the invention may also be used to implement other types ofWeb sites and applications including social networking sites havingvarious, different purposes (matchmaking, marketing, music, video, andnot necessarily collaborative or e-learning), educational sites (e.g.,Wiki, encyclopedia—analogous to Wikipedia), collaborative and e-learningsites, collaborative content development, collaborative review, desktopor on-line word processing applications, and others.

One of skill in the art would also understand that the principles of theinvention may apply to commenting on any block of data, such as Webpages or other documents, videos, pictures, files written in HTML, orother formats (text, XML, PDF, and PostScript) and rating such comments.

In a specific implementation, the system allows users to makesuggestions to a blog post. In this specific implementation, thesuggestions given to a particular blog are reflected in two placesincluding the blog owner's “suggestion received” section of the profileand the user's “suggestion given” section of the profile of the user whohas made the suggestion.

Once the suggestion is received by the blog owner, the blog owner hastwo options to make including approve the suggestion or discard thesuggestion. When the suggestion is received, the status of thesuggestion will be “approval pending.” Once the suggestion is approved,the status changes to “approved.” If the suggestion is discarded, thestatus changes to “discarded.” Only the blog owner is allowed to approveor discard the suggestion. The other users can only view the suggestion.

The “make a suggestion” feature is initiated when the EnglishCafe (EC)user feels that he would like to suggest an alternative way to expressthings that the user might have used. In an implementation, it is doneby selecting the text for which the user wants to suggest and givingyour suggestion to it. In a specific implementation, the user who wouldlike to make a suggestion is an EC user.

An example of the flow to make a suggestion is as follows.

1. The EC user reads a blog post.

2. The user finds that the blog has spelling error.

3. The user wants to suggest the blog owner that the text has a spellingerror.

4. The user selects the text having the spelling error using the cursor.

5. A pop-up window of toolbox opens up.

6. There are five options in the toolbox. Select the “make a suggestion”option.

7. Another window opens up which will be as displayed below.

8. The selected text from the blog will be highlighted in red in the“selected text” textbox. Beneath that is the “type your suggestion”textbox where the user should type the text that he is suggesting. Bydefault, the cursor will be in this textbox. Beneath that is the“explain your suggestion” textbox in which the reason for the suggestionis to be filled in; however, this textbox is optional.

9. Once the details have been filled in the boxes, a “submit mysuggestion” button is clicked to submit.

10. Once the suggestion is made, the toolbox will now appear on theright side of the blog with a link “current suggestion.” It appearswhenever a suggestion is made and allows users to make suggestions onblog post and suggestions on what others have suggested as well. Fromthis toolbox at the right side, the user can view the suggestions madeand also edit the suggestion if needed from the “edit my suggestion”option available at the top right of the suggestion window.

11. When the suggestions submitted are viewed by a user from thistoolbox which is at the right side of the blog, the suggestion that iscurrently showing will be highlighted by a red line in the blog.

12. This option “make a suggestion” will not be enabled for an anonymoususer and the blog owner.

In a specific implementation, each paragraph has a unique paragraphidentifier, which is generated by server side code Personal Home Page(PHP). In this specific implantation, highlighting (e.g., underlining)the content selected by the user uses the paragraph identifier, startword count and end word count.

Once the suggestion is submitted, it will sit in the “suggestionsreceived” section of the blog owner's profile. This suggestion will alsobe seen in the “suggestions given” section of the user's profile who hasgiven the suggestion. The blog owner can then view the suggestion fromthe “suggestions received” and has the privilege to approve thesuggestion or discard the suggestion. The status of the suggestion willbe “approval pending” at the beginning when the suggestion has beensubmitted.

When “approval pending” is clicked, the page is directed to the blogpost page where the suggestion has been given with highlighting thesuggestion text by red line. The blog owner has now the option of“approve” and “discard.” If the suggestion is approved, the status inthe suggestions received inbox will be “approved” or “discarded” if thesuggestion is discarded. In this specific implementation, only the blogowner has the rights to approve or discard the suggestion.

When the suggestions are edited by the blog owner, “suggestion history”link will be generated in the toolbox below the “current suggestion.”When clicked on the suggestion history, it will show the suggestionswith their status.

A suggestion given by a user may overlap with another suggestion givenby another user. For example, if there is a suggestion 1 for paragraph 1and the there is suggestion 2 for a part of paragraph 1. Initially, thestatus for both the suggestions will be “approval pending.” When thesuggestion 1 is approved by the blog owner, then suggestion 2 have thestatus changed to “agree pending” from “approval pending.” Thesuggestion 1 will now have the status as “approved.” It is the blogowner's decision to agree upon the suggestion 2 or discard it,accordingly the status will be changed to agreed or discarded.

When the overlapping suggestions are viewed from the “currentsuggestion” option of the toolbox, the current suggestion selected willbe highlighted in red line and the overlapped suggestion will behighlighted in red with dotted lines.

In a specific implementation, the blog content is dynamically changed tothe updated content when the page is refreshed by the user, when thesuggestion is approved, discarded, agreed to, or agree pending by theblog owner, and when the toolbox is closed by the user.

In a specific implementation, the system tracks new or unviewed contentand displays a visual indicator of new or unviewed content. In thisspecific implementation, the visual indicator includes an asterisk(e.g., orange asterisk). Thus, content which has not yet been viewedwill be displayed with an orange asterisk symbol. The orange asterisksymbol will appear for every logged user for the new suggestions posedby other users.

FIG. 4A shows a block diagram of a specific implementation of a systemof the invention. This system includes any number of clients such asfirst and second clients 403 and 406 which access a server 409 via acommunication network 412. The communication network is as shown in FIG.1 and described above.

The clients are general purpose computers with hardware and software,such as shown in FIGS. 2-3 and described above. The clients include oneor more hardware and software components described. For example, thefirst client includes a first display 415, a first application program418 (e.g., first browser application program), a pointing device,processor, memory, and storage. Similarly, the second client includes asecond display 421, a second application program 424 (e.g., secondbrowser application program), a pointing device, processor, memory, andstorage. The clients execute executable code (or computer-readable code)that embodies a technique or algorithm as described in this application.The browser is an application program that can request, receive, andprocess data from a user, the server, or both. The data can be shown viathe first display.

The server includes components similar to the components shown in FIG. 3and described above. For example, the server includes a processor,memory, applications 427, and storage 430. In a specific implementation,the storage includes e-learning course content 433, Web content 436,user Web pages 439, and databases 442. The e-learning course content isoptional and is not included in other implementations.

An application such as a Web server 445 delivers Web pages (e.g., userWeb pages) and other data from the storage to the browsers. An exampleof a Web server includes the Apache Web server from the Apache SoftwareFoundation. In a specific implementation, the applications include ane-learning application or system 448. The e-learning applicationinteracts with the e-learning course content to provide an e-learning oron-line learning experience for individual users. Variousimplementations of the e-learning application and e-learning coursecontent are described in U.S. patent application Ser. Nos. 11/160,098,filed Jun. 8, 2005, and 11/164,726, filed Dec. 2, 2005, which areincorporated by reference along with all other references cited in thisapplication.

FIG. 4B shows an example of two users making suggestions to contentwhere the content creator accepts one of the suggestions. A flow forthis example is as follows. Some specific flows are presented in thisapplication, but it should be understood that the invention is notlimited to the specific flows and steps presented. A flow of theinvention may have additional steps (not necessarily described in thisapplication), different steps which replace some of the steps presented,fewer steps or a subset of the steps presented, or steps in a differentorder than presented, or any combination of these. Further, the steps inother implementations of the invention may not be exactly the same asthe steps presented and may be modified or altered as appropriate for aparticular application or based on the data.

1. First user (or user A) creates content.

2. Second user (or user B) accesses the content, selects a portion ofthe content, and makes a first suggestion for the selected content.

3. Third user (or user C) access the content, selects a portion of thecontent, and makes a second suggestion for the selected content.

4. User A accesses the stored first and second suggestions and approvesone of the two suggestions.

5. The selected content is replaced with the approved (or accepted)suggestion.

More specifically, in the first step, user A is at a computer (e.g.,desktop, laptop, smartphone, tablet computer, or any kind of portable ornon-portable electronic device) and creates content such as paragraphs450 a and 450 b. In a specific implementation, user A creates thecontent as part of a blog post. The content may be created using anytype of input device such as a keyboard, mouse, stylus, or combinationsof these. The keyboard may be a physical keyboard or keyboard that isdisplayed on an electronic screen such as an electronic touchscreen ortouch-sensitive screen. A touch-sensitive screen may include handwritingrecognition software to allow the user to provide input by writing onthe touchscreen using a finger (or fingertip), digital pen, stylus, orcombinations of these.

After user A creates the content, the content is transmitted 452 to aserver 454. The content is stored at the server which is remote fromuser A's computer. In this specific implementation, the content isstored in a first database 456 (or in a table of the first database)that is at the server. The table includes a paragraph identifier field458 and a content field 460. The paragraph identification field storesparagraph identifiers 100 and 101 which correspond to paragraphs 450 aand 450 b, respectively. The content field stores the content (orparagraph content) of paragraphs 450 a and 450 b.

In the second step, user B accesses 462 the content created by user A.For example, user B may access the content using a Web browser programthat displays a document (e.g., Web page blog) which includes thecontent created by user A. User B may be a regular reader or follower ofuser A's blog. The system may send notifications to followers of userA's blog when there is new activity such as when user A makes a new blogpost. Examples of notifications include e-mail, text messages, tweetsvia Twitter, and so forth.

User B can view, review, or read the content created by user A. Whenuser B wishes to make a suggestion, user B selects a portion 464 of thecontent (shown in FIG. 4B as underlining). The system prompts, requests,or seeks a first suggestion 465 from user B. User B makes the suggestionusing an input device (e.g., keyboard) and submits the first suggestion.

The first suggestion is transmitted 466 to the server and is stored atthe server. In this specific implementation, the first suggestion isstored in a second database 468 (or in a table of the second database)that is at the server. The table includes a paragraph identifier field470, a suggestion identifier field 472, a suggestion field 474, and aposition field 476.

Paragraph identifier field identifies the paragraph in which asuggestion was made. In this example, the paragraph identifier fieldindicates that a suggestion was made in paragraph 450 b whichcorresponds to paragraph identifier 101. The paragraph identifier may bereferred to as a content identifier.

The suggestion identifier field identifies the suggestion identifier(e.g., 200) which corresponds to first suggestion 465. The suggestionfield stores the first suggestion.

The position field identifies a location or position of the selectedcontent within the paragraph. In a specific implementation, the systemassigns first and second numerical values for each word in a paragraph.The first numerical value indicates a beginning position of a word inthe paragraph. The second numerical value indicates an ending positionof the word in the paragraph.

Thus, in this specific implementation, a number of positions within aparagraph is equal to a number of words in a paragraph plus one.Alternatively, a number of positions within a paragraph may be equal toa number of character groups in the paragraph plus one. A charactergroup may include one or more characters or consecutive characters thatare not spaces. For example, paragraph 450 b which is associated withparagraph identifier 101 has 25 words (or 25 character groups) and thushas 26 positions. These positions are shown below and indicated by thebracketed numbers:

-   -   [1]Well,[2]I[3]was[4]lucky[5]enough[6]to[7]be[8]invited[9]back[10]this[11]year[12]as[13]a[14]judge.[15]For[16]3[17]weeks[18]I[19]regularly[20]was[21]delivered[22]with[23]chocolate[24]samples.[25]Yum![26]

Thus, the selected portion of the content, i.e., “For 3 weeks Iregularly was delivered with chocolate samples.” has a start position of[15] and an end position of [25]. The selected portion of content isbetween the start and end positions. The start and end positions arestored in the position field. As one skill in the art would recognize,the position field may be divided into two separate fields—a startposition field and an end position field—where the start position fieldstores the start position and the end position field stores the endposition.

Position information may be anything or any arbitrary reference thatpermits referencing a beginning position of a selection of content, anending position of the selection of content, or both. For example, inanother specific implementation, the system assigns a numerical value toeach word in a paragraph. Using paragraph 450 b as an example, the wordsin the paragraph are identified as follows:

-   -   [1]Well,[2]I[3]was[4]lucky[5]enough[6]to[7]be[8]invited[9]back[10]this[11]year[12]as[13]a[14]judge.[15]For[16]3[17]weeks[18]I[19]        regularly[20]was        [21]delivered[22]with[23]chocolate[24]samples.[25]Yum!

In this specific implementation, the word “Well,” (or character group)is assigned the bracketed number [1], the word “I” is assigned thebracketed number [2], the word “was” is assigned the bracketed number[3], and so forth. Thus, the selected portion of the content, i.e., “For3 weeks I regularly was delivered with chocolate samples.” has a startposition of [15] which is assigned to the word “For” and has an endposition of [24] which is assigned to the word “samples.”

In another specific implementation, the system assigns numerical valuesor references to the spaces within the paragraph for locating aselection of content within the paragraph. For example, the selectedportion of content, i.e., “For 3 weeks I regularly was delivered withchocolate samples.” may be referenced as being between a first spacehaving a space assignment value of [15] and a second space having aspace assignment value of [25]. In various implementations, a methodincludes one or more steps of assigning a numerical sequential value toeach space within a paragraph where the suggestion is being made,assigning the first position a numerical value for a space within theparagraph equal to or immediately preceding the first position,assigning the second position a numerical value for a space within theparagraph equal to or immediately after the second position, assigning anumerical sequential value to each character within a paragraph wherethe suggestion is being made, assigning a numerical sequential value toeach character within the content where the suggestion is being made, orcombinations of these.

In a specific implementation, the numerical values or references areassigned at a beginning of the paragraph. However, as discussed above,position information may be anything or any arbitrary reference thatpermits referencing a selection of content. For example, in anotherimplementation, a value is assigned starting at an end of the paragraphand the system counts backwards from the end of the paragraph towardsthe beginning of the paragraph to assign position information. Inanother implementation, a value is assigned starting at some arbitrarypoint in the paragraph, such as in a middle of the paragraph and thesystem counts backwards from the arbitrary point to the beginning of theparagraph, and counts forwards from the arbitrary point to the end ofthe paragraph to assign position information.

In a specific implementation, values (e.g., first and second numericalvalues) are with respect to words in a paragraph, or are with respect toa beginning position of a word and an ending position of the word. Forexample, using paragraph 450 b as an example, the word “Well,” isassigned first and second numerical values of [1] and [2], respectively.The word “I” is assigned first and second numerical values of [2] and[3] respectively. The word “was” is assigned first and second numericalvalues of [3] and [4], respectively.

This can help facilitate selecting content in the paragraph to make asuggestion. For example, the system detects that a user has selected aportion of a word. In a specific implementation, the systemautomatically selects the whole word. That is, the second numericalvalue that is stored is the numerical value corresponding to the end ofthe whole word (or the numerical value corresponding to the beginning ofthe subsequent word, i.e., the word after the whole word). Thus, to makea selection, the user does not have to completely select every word inthe selection. This can help persons with disabilities who may not havethe dexterity with an input device (e.g., mouse) to make completeselections.

In another implementation, the system automatically deselects the wholeword. That is, the second numerical value that is stored is thenumerical value corresponding to the beginning of the whole word (or thenumerical value corresponding to the end of the previous word, i.e., theword before the whole word). This can be a benefit in cases where theuser did not intend to select the word as part of the selection to makea suggestion.

In another implementation, the first and second numerical values arewith respect to characters in a paragraph. That is, in this specificimplementation, the system assigns for each character in a paragraphfirst and second numerical values. The first numerical value indicates abeginning position of a character in the paragraph. The second numericalvalue indicates an ending position of the character in the paragraph.Using paragraph 450 b as an example, the characters in the paragraph areidentified as follows:

-   -   [1]W[2]e[3]l[4]l[5],[6]I[7]w[8]a[9]s[10]l[11]u[12]c[13]k[14]y[15]e[16]n[17]o[18]u[19]g[20]h[21]t[22]o[23]b[24]e[25]i[26]n[27]v[28]i[29]t[30]e[31]d[32]b[33]a[34]c[35]k[36]t[37]h[38]i[39]s[40]y[41]e[42]a[43]r[44]a[45]s[46]a[47]j[48]u[49]d[50]g[51]e[52].[53]F[54]o[55]r[56]3[57]w[58]e[59]e[60]k[61]s[62]I[63]r[64]e[65]g[66]u[67]l[68]a[69]r[70]l[71]y[72]w[73]a[74]s[75]d[76]e[77]l[78]i[79]v[80]e[81]r[82]e[83]d[84]w[85]i[86]t[87]h[88]c[89]h[90]o[91]c[92]o[93]l[94]a[95]t[96]e[97]s[98]a[99]m[100]p[101]l[102]e[103]s[104].[105]Y[106]u[107]m[108]![109]

Thus, for example, the selected portion of the content, i.e., “For 3weeks I regularly was delivered with chocolate samples.” has a startposition of [53] which is assigned to the beginning position of thecharacter “F” in the word “For” and has an end position of [104] whichis assigned to the ending position of the character “s” in the word“samples.” In the above example, the spaces between words have beenomitted for clarity. However, it should be appreciated that spaces maybe considered to be characters and be assigned position information sothat the beginning position and ending position of a space may beidentified.

Assigning position information based on characters allows a user toselect a portion of a word. This specific implementation can permit auser to select a portion of a word. For example, a user can select theletters “W” and “e” in which case the first and second numerical valuesare [1] and [3], respectively. This specific implementation may bebeneficial where a user desires granularity, i.e., the ability to selectone or more characters in a word. For example, if user A inputted theword “thier,” user B can correct the misspelled word by selecting thecharacters “ie” and making the suggestion “ei.”

In implementations discussed above, position information is assigned atthe paragraph level or with respect to a paragraph. However, positioninformation may be assigned at the document level. For example, in aspecific implementation, the system assigns for each word in a documentfirst and second numerical values. The first numerical value indicates abeginning position of a word in the document. The second numerical valueindicates an ending position of the word in the document. For example,the document shown in FIG. 4B having the paragraphs 450 a and 450 bwould have the following assigned position information:

-   -   [1]Remember[2]the[3]San[4]Francisco[5]Chocolate[6]Salon[7]I[8]attended[9]last[10]year?[11]    -   Well,[12]I[13]was[14]lucky[15]enough[16]to[17]be[18]invited[19]back[20]this[21]year[22]as[23]a[24]judge.[25]For[26]3[27]weeks[28]I[29]regularly[30]was[31]delivered[32]with[33]chocolate[34]samples.        [35]Yum![36]

This specific implementation can allow for a selection to be made whichspans across two or more paragraphs. For example, user B may make theselection: “attended last year? Well, I was lucky.” This selectionincludes content from paragraph 450 a (i.e., the phrase “attended lastyear?”) and content from paragraph 450 b (i.e., the phrase “Well, I waslucky”). This selection thus has beginning position of [8] and an endingposition of [15]. The beginning position indicates the location of theword “attended” in the document. The ending position indicates thelocation of the word “lucky” in the document.

Carriage returns, tabs, or both in the document may also be assignedposition information so that the system can identify where in theselection the preceding paragraph ends and the succeeding paragraphbegins.

The above technique of assigning position information with respect tothe document may be used to assign position information at the characterlevel as discussed above. For example, in a specific implementation, thesystem assigns for each character in a document first and secondnumerical values. The first numerical value indicates a beginningposition of a character in the document. The second numerical valueindicates an ending position of the character in the document.

Further, it should be appreciated that position information may beassigned based on or with respect to two or more or all the documents inthe system (e.g., position information assigned with respect to a groupof documents). Position information may be assigned based on two or moreparagraphs in a document (e.g., position information assigned withrespect to a group of paragraphs). The paragraphs may or may not beconsecutive paragraphs. Position information may be assigned based onparagraphs in separate documents. Position information may be assignedbased on sentences such as by establishing a location of periods.Position information may be assigned based on documents (or paragraphs)belonging to a user, belonging to a group of users, that are of aspecific type, and so forth. Position information may be assigned usinginformation such as a line number of a line of content in a document,page, page numbers, sections, section numbers, carriage returns, tabs,punctuation marks (e.g., periods, question marks, exclamation points,colons, semicolons, dashes, em dashes, or en dashes), or combinations ofthese.

In examples shown above, position information includes numerical valuesand specifically, sequential or consecutive positive numerical integers.However, in other implementations, the values include nonsequentialnumbers, nonconsecutive numbers, positive numbers, negative numbers,decimal numbers, nonrepeating numbers, repeating numbers, orcombinations of these.

Further, position information may instead or additionally includealphabetical characters, symbols, alphanumeric characters, punctuationmarks, or combinations of these. For example, a first value [A] mayindicate a beginning position of a selection of content. A second value[E] may indicate an ending position of the selection of content.

In a specific implementation, a selection includes two or moreconsecutive words. In another implementation, a selection includes twoor more nonconsecutive words in which a user (e.g., user B) makes asuggestion for the selection.

In the third step, user C accesses 478 the content created by user A andmakes a second suggestion 480. User C may access the content and make asuggestion by following a procedure similar to the procedure for user Bdescribed above in step 2. For example, when user C wishes to make asuggestion, user C selects a portion 482 of the content. The systemseeks second suggestion 480 from user C. User C makes and submits thesecond suggestion which is transmitted 481 to the server and stored insecond database 468. As shown in FIG. 4B, an entry is made in the seconddatabase for the second suggestion from user C. The entry includes theparagraph identifier (101) for which the suggestion was made, thesuggestion identifier (201), the second suggestion, and the positioninformation.

In this example, users C and B have selected the same portions ofcontent to make a suggestion. However, users C and B do not have tonecessarily select the same portions of content. User C may select aportion of content that is different from the portion of contentselected by user B. For example, user C may select a portion of contentfrom paragraph 450 a, user C may select a portion of content fromparagraph 450 b that does not overlap the portion of content selected byuser B, or user C may select a portion of content that at leastpartially overlaps the portion of content selected by user B.

In the fourth step, user A accesses 484 the first suggestion from user Band the second suggestion from user C. User A may receive a notificationthat a suggestion has been made to the blog post. The notification mayinclude a link to the blog post. User A can navigate to the blog post,select a link to view suggestions, and the suggestion will be displayedon user A's computer screen. User A can review the suggestion and decidewhether to approve (i.e., accept) or reject the suggestion.

That is, user A can review the first and second suggestions and decidewhich of the two suggestions to accept. User A may also decide to notaccept any suggestions, i.e., reject the first and second suggestions.

In the fifth step, when user A accepts one of the first or secondsuggestions, the selected content is replaced 486 with the selectedsuggestion. In this example, user A has accepted the first suggestionfrom user B. The system, upon receiving an indication of an acceptanceof the first suggestion, replaces the selected content with the firstsuggestion. In a specific implementation, the replacement operation mayinclude the following substeps:

5.1. Identify in first database 456 the paragraph (e.g., paragraph 450b) in which the suggestion was made using the paragraph identifier(e.g., paragraph identifier 101) that is associated with the firstsuggestion from second database 468.

5.2. Identify a location within the paragraph of the selected contentusing the start position (e.g., [15]) and end position (e.g., [25]) ofthe selected content.

5.3. Extract from the paragraph the content between the start and endpositions—the extracted content being the selected content.

5.4. Insert the first suggestion between the start and end positions.

5.5. Store the updated paragraph with the first suggestion havingreplaced the selected content in the first database.

When users navigate to user A's blog post or otherwise access the blogpost, the users will see a document or Web page 488 having the updatedparagraph. In a specific implementation, an operation where the selectedcontent is replaced by the first suggestion includes inserting the firstsuggestion into the first paragraph and deleting the selected contentfrom the first paragraph. The deleting the selected content may bebefore, after, or during the inserting the first suggestion into thefirst paragraph. The selected content may be overwritten by the firstsuggestion. In another specific implementation, the operation where theselected content is replaced by the first suggestion includes swappingthe selected content in the first paragraph with the first suggestion.

As discussed above and elsewhere in this application, a feature of aspecific implementation of the invention is to allow collaboration ofmultiple users to view and make suggestions on the same document. Insuch an implementation, the user will not receive a message such as“document is locked for editing (or viewing) by another user.” Thecontent creator may be editing the content, while other users isreviewing and making comments or entering suggestions at the same timeas each other, or different times. For example, a first user may enter asuggestion at the very same time the second user is entering a differentsuggest to the same page, or even the same selected text. The databaseorganization that facilitates this feature is described in FIG. 5 andthe accompanying text, and elsewhere in this application.

Further, a user may view, access, and accept suggestions even if theusers who made the suggestions are not connected or are disconnectedfrom the system or network. The suggestions are stored or saved in forexample, a database or file (see FIG. 5 below and accompanying text). Ina specific implementation, user A accesses or views user's B'ssuggestion. While user A is viewing or accessing user B's suggestion,user B can be disconnected from the system. When user B is disconnectedfrom the system, user A accesses B's suggestion as it was saved in thedatabase or file. User may choose to password protect, encrypt thedocument, or other protect the document so that the document is viewableby only selected users (e.g., particular groups or friends of user A,which are authorized by A). In another implementation, user A can senduser B (and perhaps many other people) an e-mail with a link to thedocument. After hitting the link, if user B is not recognized as beingauthorized to view the document, the system can send a message to Ainquiring whether B is allowed to access. Then, the users (B and perhapsmany others) can review the document and make any comments orsuggestions, without conflict or waiting for others to finish makingtheir comments. The document can be viewed through, for example, an SSLencrypted link (or other encryption technology including RSA, HTTPS, andso forth), where an SSL or other certificate is used to securely link Bto the document. Any suggestions of comments user B makes will beencrypted, so eavesdroppers cannot see the document or comments. User Bcan also use one or multiple languages in making the comments. Thesystem of the invention may operation in one or multiple languagesincluding English, French, German, Spanish, Chinese characters, Japanesecharacters, Mandarin, Korean, and others.

Similarly, users may make suggestions to content even if the contentcreator is disconnected from the system. In a specific implementation,user B makes a suggestion to content created by user A. User A may alsobe also referred to as the content organizer, content moderator, contentowner, content creator, content provider, creator, owner, author, pageadministrator, page master, provider, or other terms. In this patent,user A is a user who has the authority to authorize adding, deleting,replacing, and changing of content. Although user A may be referred toas a content author or content owner, user A may not actually havecreated the content or be the author. For example, user A may includesome passages from Charles Dickens or Jules Verne on user A's page.Rather user A is an owner of the page, so user A has the authority tochoose what content is include on user A's pages, and whether anychanges (e.g., via suggestions) can be made to that page. In aparticular implementation, user A may grant privileges to other users,which may be referred to as subordinate page owners who are given theability to accept or decline changes to a page. Content may also havejoint owners: If two or more users can authorize changes where anauthorization from any one of the joint owners approves changes. In someother implementations, every joint owner must agree to authorize beforea change will be made. In some other implementations, a majority orquorum of joint owner must agree to authorize before a change will bemade.

While user B is making the suggestion, user A is disconnected from thesystem. These features of the system can help to facilitatecollaboration among users who may have different work schedules, workingremotely from the office, be in different time zones or parts of theworld. For example, user A who may be in California, can view and accepta suggestion made by user B who may be asleep in Russia and notconnected to the system, i.e., off-line or not online. User B can make asuggestion to content created by user A while user A is asleep and notconnected to the system.

Thus, in this specific implementation, users can make suggestions tocontent while the content creator is not connected to the system. A usercan view suggestions, accept suggestions, or both while the users whomade the suggestions are not connected to the system. In various otherimplementations, both user A who created the content and user B who madethe suggestion to the content must be connected to the system for user Ato view the suggestion, accept the suggestion, or both. User A whocreated the content must be connected to the system for user B to make asuggestion to the content.

In a specific implementation, user B selects a first portion of contentto make a first suggestion, user C selects a second portion of contentto make a second suggestion, and the first and second portions at leastpartially overlap. After user A accepts one of the first or secondsuggestions to replace one of the first or second portions, user A isnot permitted to later accept the not accepted first or secondsuggestion. In other words, the system does not make a replacement ofone of the first or second portions with the not accepted first orsecond suggestion. The system may send a notification to the user whosesuggestion was accepted to inform the user that the suggestion wasaccepted. The system may send a notification to the user whosesuggestion was not accepted to inform the user that the suggestion wasnot accepted.

In another implementation, after user A accepts one of the first orsecond suggestions to replace one of the first or second portion, user Ais permitted to later accept the not accepted first or secondsuggestion. When user A later accepts the not accepted first or secondsuggestion, the system undoes the replacing of the first portion withthe first suggestion and replaces the second portion with the secondsuggestion. This feature may be helpful when, for example, user Achanges her mind and decides that even though she accepted one of thesuggestions, user A now prefers the other suggestion.

In a specific implementation, a user can make a suggestion to a portionof content where the portion of content includes at least a portion ofanother suggestion. For example, in this specific implementation, user Bselects a first portion of content to make a first suggestion. User Aaccepts the first suggestion and the first portion of content isreplaced with the first suggestion. After the first portion of contentis replaced with the first suggestion, user C selects a second portionof content to make a second suggestion. The second portion of contentincludes at least a portion of the first suggestion. User A accepts thesecond suggestion and the second portion of content is replaced with thesecond suggestion.

A user may be able to edit her suggestion after the suggestion issubmitted and before the suggestion is accepted. For example, user Bselects a portion of the content and makes a first suggestion. Beforeuser A accepts the first suggestion, user B decides that she want tosuggest something different from the first suggestion or edit the firstsuggestion. User B edits the first suggestion. In a specificimplementation, user A is permitted to access the edited firstsuggestion, but not the unedited first suggestion. When user A acceptsthe edited first suggestion the edited first suggestion replaces theselected portion of content. In another implementation, user A ispermitted to access the edited first suggestion and the unedited firstsuggestion. User A can accept one of the edited first suggestion orunedited first suggestion. When user A accepts one of the edited firstsuggestion or unedited first suggestion, the selected portion of contentis replaced with the accepted edited first suggestion or unedited firstsuggestion.

The example shown in FIG. 4B shows two users (users B and C) makingsuggestions to content created by another user (user A). However, itshould be appreciated that there can be any number of users makingsuggestions to content created by another user. For example, there canbe three, four, five, six, seven, eight, nine, ten, or more than tenusers making suggestions to the content created by user A.

Further, a user may make any number of suggestions. For example, user Bmay make a third suggestion to the content created by user A. User B maymake a third suggestion to a selected portion of content where theselected portion of content may include at least a portion of asuggestion from user C, user B, or both. User B may make two or moresuggestions to a selected portion of content so that user A can selectfrom among the two or more suggestions. For example, user B may which toprovide user A with several alternative suggestions. Thus, user Bselects a portion of content created by user A and makes first andsecond suggestions. User A access the first and second suggestions andselects one of the first or second suggestions. The portion of contentis replaced with the selected first or second suggestion.

A feature of the system is to help facilitate interaction,participation, and collaboration among members of a community or socialcommunity. In a specific implementation, this feature is implemented ina social networking community and provides an immersive andcollaborative environment for learning a new language. The system makesit easy for user A to incorporate or use a suggestion from user B. Thus,user B who is reviewing content created by user A may feel more inclinedto participate and offer meaningful and helpful suggestions.

The system may include features such as public discussion groups,private discussion groups (e.g., a my friends group), e-mail, instantmessaging, video chat, photo and video albums, a question and answerforum, or any other social networking tool, or combinations of these.Such tools can allow users to share ideas, activities, events, andinterests. These tools can provide a way for users to connect with otherusers having similar interests. Thus, users may see or interact withother users in a variety of contexts on the system. This can furtherdevelop a sense of trust among the community members and foster a senseof belonging to a community, which in turn further promotescollaborative interaction.

In a specific implementation, the system includes a ratings mechanismwhich keeps track of which suggestions were accepted, which users madethe accepted suggestions, and assigns a point to a user whose suggestionwas accepted. The ratings mechanism may allow users to rate or grade thesuggestions made by other users.

This can foster a friendly spirit of competition among members of thecommunity to see who can receive the most points or highest score. Sincepoints are awarded for accepted suggestions and are not awarded forunaccepted suggestions, this can further help to encourage users to makemeaningful and helpful suggestions, which in turn encourages users tofurther create content to be reviewed.

Users having a high number of points may be recognized by having theirnames displayed on a scoreboard or leaderboard Web page of the systemfor other users to see and admire. Users having a high number of pointsmay be redeem their points for prizes or be awarded prizes such as cash,electronic gadgets, toys, books, candy, or other goods, products, orservices. This can further incentivize users to participate throughmeaningful and helpful suggestions.

As one of skill in the art would recognize the implementation discussedabove is merely one particular implementation for making a suggestion(or annotating) a portion of content and replacing the selected contentwith the suggestion or annotation. In a specific implementation, contentis identified by sentence. In another specific implementation, insteadof using position information in a paragraph to identify selectedcontent, the system performs a text matching search. For example, theselected content within a paragraph may be copied and stored. When theselected content is to be replaced with the suggestion, the system mayperform a text search of the paragraph using the selected content toidentify which text should be replaced with the suggestion.

In a specific implementation, the system is designed so that usersselect whole words rather than a portion of a word. This can help toensure that suggestions are meaningful since a suggestion to a portionof a word may not be helpful. In another implementation, the system isdesigned so that a user can select a portion of a word. For example,position information in a paragraph may correspond to the position ofindividual characters in a paragraph, rather than words in a paragraph,so that the user can select a portion of a word. In a specificimplementation, users make selections within a paragraph. This can helpto ensure that suggestions do not become too unwieldy (i.e., user makesa selection having 500 words). In another implementation, users can makea selection across two or more paragraphs.

In this specific implementation, the content includes text. In otherimplementations, the content includes audio, video, images, pictures, orcombinations of these. If, for example, the content includes a video,the selected content may be identified by one or more frames of thevideo. A selected portion or fragment of the video may be identified bya begin time of the video fragment and an end time of the videofragment. If the content includes audio or an audio track, for example,a selected portion of the audio track may be identified by a begin timeof the audio fragment and an end time of the audio fragment.

In a specific implementation, the system can automatically select awhole or entire word, a whole sentence, or a whole paragraph. Forexample, in various implementations, user B selects a word and clicks(e.g., click or double clicks on the word) and the system selects thewhole word. User B selects a portion of a sentence and clicks (e.g.,click or double clicks on the sentence) and the system selects the wholesentence, user B selects a portion of a paragraph and clicks (e.g.,click or double clicks on the selected portion of the paragraph) and thesystem selects the whole paragraph. If the selection spans two or moreparagraphs, the system selects the entire of the two or more paragraphs.

This can help speed the time it takes for a user to select whole words,sentences, or paragraphs. For example, the user does not have to dragtheir mouse over the whole word. To detect a whole word, the system candetect the beginning and ending position of a word by selectingbackwards from the selected portion of the word until a space before theword is reached and selecting forwards from the selected portion of theword until a space after the word is reached. To detect a whole sentencethe system can select backwards from the selected portion of thesentence until a period is reached, a capital letter is reached, a setof double spaces is reached, or anything else that would indicate theend of the previous sentence. The system can then select forwards fromthe selected portion of the sentence until an indication that an end ofthe sentence has been reached. The beginning and ending positions ofsentences can be determined by looking for or searching for punctuationmarks (e.g., periods, exclamation points, question marks, and the like).To detect the beginning and ending positions of a paragraph, the systemcan search for tabs, carriage returns and so forth that would indicate,for example, the end of a previous paragraph and the beginning of asubsequent paragraph.

In a specific implementation, users can insert carriage returns in theirsuggestions. When the suggestion is accepted the carriage return appearsin the updated content.

In a specific implementation, a user after making a selection can maketwo or more alternative suggestions. For example, user B can select aportion of the content. The system the prompts user B for a firstsuggestion and a second (i.e., alternative) suggestion. The systemstores both suggestions. User A can then accesses the first and secondsuggestions and decide which one, if any, to accepted. The selectedportion of content will be replaced with the accepted suggestion.

FIG. 5 shows a specific implementation of various data structures forsome of the information stored in the storage of the server shown inFIG. 4A and shows some further details of the example shown in FIG. 4B.Server 409 includes a storage 505 for user Web pages, such as Web pages508 a, 508 b, and 508 c, a suggestions database 510, a suggestionsidentification database 511, and a suggestions history database 513.

The Web pages show examples of suggestions 511 having been made atvarious specific locations within the Web page. A suggestions table 516shows a data structure used to store information such as suggestions inthe suggestions database. A suggestions identification table 519 shows adata structure used to store information in the suggestionsidentification database. A suggestions history table 520 shows a datastructure used to store information in the suggestions history database.The tables can include any number of fields.

In an implementation, when user B makes suggestions to user A'sdocument. A's document is stored in user web pages 505, while user B'ssuggestion is stored in suggestion database 510, which are separatefiles or locations. This means that the suggestion is not stored withthe document to which the suggestion was made. This organization of thedata allows multiple users to view, edit, and make suggestions at thesame time. So users will not receive a file is locked message, thatdisallows their making edits or suggestions. Also in this example, webpages 505 is referred to a “web” pages. The invention does not onlyapply to “web” pages, but also to other types of documents, not justonly web pages. These documents can be accessible through the Internetor other network, such as an intranet.

In a specific implementation, the suggestions table stores suggestions.The suggestions identification table identifies the user who made thesuggestion and the type of user-generated content (e.g., blog entry orforum post) that the suggestion is associated with. The suggestionshistory table tracks which users viewed the suggestion and when the userviewed the suggestion.

In this specific implementation, the tables are each in separatedatabases. However, in another specific implementation, the tables arein a single database. The single database is a common database (e.g.,MySQL version 5.0.5) which stores the suggestion, suggestionidentification, and suggestions history tables. A SQL database is merelyone type of database and other databases or file structures may be usedincluding database products from Oracle, Microsoft, IBM, and Google(e.g., Google spreadsheet).

The system allows users to create content. This user created content isthen displayed on a Web page such as Web page 508 a for other users tosee. The system allows one or more of these other users to select aportion of the content at a specific location 522 within the content,and make an annotation or suggestion 555 a (e.g., remark or comment) tothat selected content.

Users can see the suggestions made by other users and identify whichportion of the content the suggestion is associated with. The user whoauthored or created the content (i.e., content author) can review thesuggestion and, if desired, make changes or edits to the suggestion. Thecontent author can then accept (e.g., approve) or reject (e.g., discard)the suggestion. If the content author accepts the suggestion the systemreplaces the selected portion of the content with the suggestion. Theuser created content on Web page 508 a is updated such that the portionof the content at the specific location within the content is removed orno longer visible having been replaced with the suggestion. If thecontent author rejects the suggestion the Web page stays the same. Thatis, the system does not replace the portion of the content with thesuggestion.

Any number of suggestions can be made by any number of users to anynumber of user created content. Furthermore, any number of suggestionscan be made by any number of users to a selected portion of the content.That is, two or more suggestions can be made to the same portion ofcontent. This can be referred to as overlapping suggestions.

The user created content can be in any format or medium and can includetext, video, audio, images, pictures, graphics, or combinations ofthese. In a specific implementation, the user created content includestext inputted as part of a blog. Similarly, the suggestions includetext. A suggestion is associated with a specific portion of the blogtext which is at a specific location within the blog text.

In the example shown in FIG. 5, the tables include six entries. Eachentry is associated with one of the six suggestions shown on Web pages508 a, b, and c. In this specific implementation, suggestions table 516includes a suggestion identifier field, a suggestion field, anexplanation field, a paragraph identifier field, and a position field.

An entry 533 in suggestions table 516 includes a suggestion identifier536 in the suggestion identifier field, a suggestion 555 a in thesuggestion field, an explanation 542 in the explanation field, aparagraph identifier 545 in the paragraph identifier field, and aposition 548 in the position field.

The suggestion field includes a text string (e.g., ASCII text string)that represents the suggestion inputted by the user. The user inputtingthe suggestion may be referred to as the suggester. Input may be typedin using a keyboard, keypad, stylus, or other human input device, or mayalso be entered using other techniques, such as selecting from amongsome displayed suggested choices, or combination of suggested choices;scanned, video, camera or photo input, and video or image (e.g., pictureor photo) to text conversion; or voice recognition or real-time speechrecognition. U.S. Pat. Nos. 6,453,290, 6,865,536, 7,330,815, and7,689,415, which are incorporated by reference, describe network-basedspeech recognition. Speech or voice recognition may be performed by thedevice, where the recognition routines are executed (at least in part orentirely) on the device.

The explanation field includes a text string that represents theexplanation inputted by the suggester (i.e., suggester explanation forthe suggested text). That is, when the suggester makes the suggestionthe system allows the suggester to input an explanation or reason forthe suggestion. Inputting the explanation is optional. The suggester cansubmit a suggestion without having to input an explanation. In this casethe explanation field for this entry in the table will be empty.

The suggestion identifier and paragraph identifier fields may includeunique series of numbers, characters, letters, or combinations of these(e.g., alphanumeric). Each of the suggestions may be associated with aunique suggestion identifier. This allows referencing a suggestion viaits suggestion identifier. As an example, suggestion identifier 536 isassociated with suggestion 555 a. A suggestion identifier 554 isassociated with suggestion 555 b, and so forth. The suggestionidentifier is generated automatically for every suggestion made.

In this specific implementation, the suggestion identifier may be uniqueacross all of the suggestions. Thus, a first suggestion identifier forsuggestion 555 a in Web page 508 a will be different from a secondsuggestion identifier for suggestion 555 b in Web page 508 b anddifferent from a third suggestion identifier for suggestion 555 c in Webpage 508 b. The second suggestion identifier will be different from thethird suggestion identifier. In another implementation, the suggestionidentifier is unique with respect to a specific Web page. Thus, in thisspecific implementation, the first suggestion identifier, which isassociated with suggestion 555 a in Web page 508 a, may the same as thesecond suggestion identifier, which is associated with suggestion 555 bin Web page 508 b.

Each of the paragraphs may be associated with a unique paragraphidentifier. This allows referencing a paragraph via its paragraphidentifier. A Web page can have any number of paragraphs.

In this specific implementation, the paragraph identifier is uniqueacross all the paragraphs in all of the Web pages. Thus, a firstparagraph identifier is associated with a first paragraph in Web page508 a. A second paragraph identifier is associated with a secondparagraph in Web page 508 a. A third paragraph identifier is associatedwith a third paragraph in Web page 508 b. The first paragraph identifieris different from the second and third paragraph identifiers. The secondparagraph identifier is different from the third paragraph identifier.In another implementation, the paragraph identifier is unique withrespect to a specific Web page. Thus, in this specific implementation,the first paragraph identifier is different from the second paragraphidentifier, but may be the same as the third paragraph identifier.

The position field includes integer values. In a specificimplementation, the position includes a start position field and an endposition field. The start position indicates a start position of aselected portion of content (e.g., a start position of a selected textwithin a paragraph). The end position indicates an end position of theselected portion of content (e.g., an end position of the selected textwithin the paragraph).

In a specific implementation, the number of positions within a paragraphis equal a number of words in a paragraph plus one. For example, aparagraph having four words will have five positions. A first word ofthe paragraph starts at a first position and ends a second position. Asecond word of the paragraph starts at the second position and ends at athird position. A third word of the paragraph starts at the thirdposition and ends at a fourth position. A fourth word of the paragraphstarts at the fourth position and ends at a fifth position.

In this specific implementation, the selected text can include anynumber of consecutive words within the paragraph. For example, a firstselected text can include the first word. A second selected text caninclude the first, second, and third word. A third selected text caninclude the second and third word, and so forth. Thus, the firstselected text will have a start position at the first position and anend position at the second position. The second selected text will havea start position at the first position and an end position at the fourthposition. The third selected text will have a start position at thesecond position and an end position at the fourth position.

In other implementations, a selected text includes any number ofnonconsecutive words, a combination of consecutive words andnonconsecutive words. The selected text may include one or more words,characters, letters, spaces, symbols, punctuation marks, word dividers,or any type of typography, and combinations of these. The selected textcan include content from two or more paragraphs. The two or moreparagraphs may be consecutive or nonconsecutive.

In a specific implementation, suggestions table 516 includes five fieldsor columns. These five fields and a brief description of each field areshown below in table A.

TABLE A Field Name Description Original_content The original text forwhich a suggestion has been made. blog_owner_(—) Content author's (orowner's) edited suggestion suggestion. Status In a specificimplementation, there are five types of values. A value of 0 indicates anew suggestion (i.e., newly received suggestion). A value of 1 indicatesthe suggestion was approved. A value of 2 indicates the suggestion wasdiscarded. A value of 3 indicates the suggestion was agreed to. A valueof 4 indicates agreement to the suggestion is pending. Date The date asuggestion was posted (i.e., made or submitted). Updated_date Date ofany updates done to the suggestion. Some examples include a date whenthe suggester edited their suggestion. A date when the author of thecontent approved, discarded, agreed with, or edited the suggestion.

Suggestions identification table 519 includes the suggestion identifierfield, a suggester identifier field, and a node identifier field. Anentry 560 in the suggestions identification table includes suggestionidentifier 536 in the suggestion identifier field, a suggesteridentifier 563 in the suggester identifier field, and a node identifier566 in the node identifier field.

The suggester identifier and node identifier fields include uniqueseries of numbers, characters, letters, or combinations of these (e.g.,alphanumeric). The suggester identifier indicates the useridentification of the user who posted the suggestion.

In a specific implementation, the node identifier is a unique number foruser-generated content (e.g., blog, video, audio, document, photo, forumcomment, question, answer, user-created group, and so forth). The nodeidentifier is cross-referenced with a node table to determine the useridentification of the creator of the node. In a specific implementation,the node table includes the user-created content in a body field of thetable. An example of the fields in the node table with descriptions foreach field is shown in table B below.

TABLE B Field Name Description Nid Node id. Vid Vid is a verifyreference number. Uid (user id) Owner of the node id. Title Title of thenode id, for example: blog title. Body Description of the title, forexample: blog content. In a specific implementation, the body includesthe user created content 710 (FIG. 7). In a specific implementation, thebody column can be updated with the selected content (e.g., selectedtext) when the suggestion is approved at the status of the suggestion ischanged to 1 in the suggestions table. In this specific implementation,the column is not updated to the suggested text when the suggestion getsdiscarded, agreed to, or agree pending. Teaser Short note of the body.Log This is site super admin usage, he can post log message about therelated node. An explanation of the additions or updates being made tohelp other authors understand your motivations. Timestamp Node createddate and time (timestamp). Format Default (allow all) = 0, Filtered html= 1, php code = 2, full html = 3.

In this specific implementation, changes or revisions to user-generatedcontent is tracked using a node revisions table. An example of some ofthe fields that may be included in the node revisions table is shown intable C below.

TABLE C Field Name Description Nid Node id. Vid Vid is a verifyreference number. Type Type of the content. Title Title of the content.Uid (user id) Owner of the node id. Status Status of the node id.Created Node created date and time (timestamp). Changed The timestampwill update when it gets any update. Comment Number of comment's countadded for this node id. Promote Promote home page. Moderate This is forsite super admin purpose(default = 0, moderate = 1). Sticky This is forsite super admin purpose(default = 0, sticky = 1). Download_count Download count of a node id. Admin_feat This is for site super adminpurpose(default = 0, admin_feat = 1). Privilege This is for site superadmin purpose(default = 0, privilege = 1). Draft_status This is for blogand news letter(default = 0, if draft = 1). Featured Set featurednode(default = 0, featured = 1).

Thus, the suggestions, suggestions identification, suggestion history,node, and node revisions tables shown above can be cross-referenced todetermine, for example, the user who submitted or posted the suggestion,the paragraph that the suggestion is associated with, the start and endposition of the text in the paragraph that the suggestion is associatedwith, and the author of the paragraph.

Suggestions history table 520 includes the suggestion identifier field,a viewer identifier field, and a time stamp field. The viewer identifierfield includes a unique series of numbers, characters, letters, orcombinations of these (e.g., alphanumeric). The viewer identifierindicates the user identification of the user who views the suggestion.

The time stamp field includes a date (e.g., year, month, and day), time(e.g., hour, minute, and second), or both. The time stamp indicates thedate and time that a user viewed the suggestion.

An entry 575 in suggestions history table 520 includes suggestionidentifier 536, a viewer identifier 578, and a time stamp 581. In aspecific implementation, an entry is made in the suggestions historytable each time a unique user views or clicks on the suggestion.Furthermore, in this specific implementation, the time stamp is updatedeach time the unique user views the suggestion.

In a specific implementation suggestions history table 520 can becross-referenced with suggestions table 516 to track which user viewedthe suggestion and the time that the user viewed the suggestion.

FIG. 6 shows a flow diagram for accessing the options from a toolbox ofthe invention. In a step 605, a toolbox is invoked. In a specificimplementation, the toolbox is invoked after the user selects a portionof the content. FIG. 7 shows an example of a selected content 705 from auser created content 710. The user created content is displayed as partof a Web page within a window of a browser application program 711.

In this specific implementation, the user selects the portion of thecontent from a paragraph using a mouse. Specifically, the user clicksthe left mouse button at a start position 715 of the portion. The userholds down the left mouse button and drags the cursor over the portion.The system responds by highlighting the portion as the user drags thecursor. The user then releases the left mouse button at an end position720 of the portion. The system detects the release of the button andinvokes a toolbox 725.

In this specific implementation, the system gathers and stores theparagraph identifier and the start and end positions of the selectedcontent. The paragraph identifier and start and end positions aretransmitted from the client to the server.

Tables D-K below show examples of code for selecting the portion of thecontent, identifying the paragraph that the content is associated with,and identifying the position or location of the selected content withinthe paragraph.

Table D below shows an example of code for the Internet Explorer browserprogram for selecting and highlighting a portion of the content.

TABLE D this.selection.createRange( ).pasteHTML(“<spanid=“range-temp”></ span>s”);

Table E below shows an example of code for the Firefox browser programfor selecting and highlighting a portion of the content.

TABLE E myParent.insertBefore(mySpan, myNodes[i][0]); //Firefox has bugsif we don't attach the span first; we can't just append it because wedon't know where it goes in the parent  Spans.push(mySpan);

Table F below shows an example of code for the Internet Explorer browserprogram for capturing the selected text where the selected text includesplain text.

TABLE F document.selection.myRange.text;

Table G below shows an example of code for the Internet Explorer browserprogram for capturing the selected text where the selected text includesHTML tags.

TABLE G document.selection.myRange.htmlText;

Table H below shows an example of code for the Firefox browser programfor capturing the selected text.

TABLE H window.getSelection( );

Table I below shows an example of code for the Internet Explorer browserprogram for obtaining the paragraph identifier.

TABLE I document.selection. selection.createRange( ).parentElement().id;

Table J below shows an example of code for the Firefox browser programfor obtaining the paragraph identifier.

TABLE J window.getSelection( ).selection.focusNode.parentNode.id;

Table K below shows an example of code for calculating the start and endpositions of the selected text.

TABLE K // This is the main part of code to calculate the start countselected text. var startCount = new Array( );    var rid_count = 0;   var start = 0;    startCount = TextArray[0].split(“ “);    if (ectoolbox_msieversion( ) >= 4) {       var start = 0;       varrid_array = Array( );       rid_array = TextArray[0].split(“jquery”);      rid_count = rid_array.length;       start = startCount.length;   } Else {       start = 0;       for(i = 0;i < startCount.length; i++){          start = start + 1;       }    }    if(rid_count > 1 && start!= 1)       start = start − (rid_count − 1);    //This is the main partof code to calculate the end count selected    text.    var endCount =new Array( );    var selected_text = str;    var amp_array = Array( );   amp_array = selected_text.split(“&nbsp;”);    selected_text =selected_text.replace(/&nbsp;/gi,” “);    selected_text =selected_text.replace(/\r/gi,”“);    endCount = selected_text.split(““);    var amp_length = 0;    if(amp_array.length > 0)       amp_length= amp_array.length − 1;    else       amp_length = 0;    vartotal_word_count = 0;    for(i = 0;i < endCount.length;i++) {      total_word_count = total_word_count + 1;    }    total_word_count= total_word_count + parseInt(amp_length);    if(total_word_count == 1)      var total_count = 1;    else    var total_count =total_word_count;    var end = 0;    if ( ectoolbox_msieversion( ) >= 4) {       end = total_count + (start − 1);    } else {       if(yes_tag== 0) {          end = total_count + (start − 1);       } else {         if(firefox_trim==0) {             end = total_count + start;      } else if(firefox_trim>0) {          end = total_count +start+firefox_trim;       } }}

In a step 610 (FIG. 6), the system draws a top view of the toolbox. Thetoolbox can be drawn at any position or location on the Web page ordocument. Typically, the toolbox is drawn such that it does not overlapthe selected content. The toolbox may overlap the nonselected content.In a specific implementation, the toolbox is drawn so that it ispositioned at or near the selected content. In this specificimplementation, the toolbox is drawn such that an upper left-hand cornerof the toolbox is positioned at or near the end position of the selectedcontent.

Generally, the toolbox is displayed in a floating window which issuperimposed over the Web page, i.e., the toolbox overlays the Web pageor appears on top of the Web page. The user can reposition the toolboxto any other position within the Web page. For example, the user, usingthe left mouse button, can select a title bar of the toolbox, drag thetoolbox to a new position, and then release the left mouse button. Inanother implementation, the toolbox is displayed in a non-floatingwindow. That is the toolbox is in a fixed position on the Web page andthe user is not able to move the toolbox to a different position.

In a step 615 (FIG. 6), the system shows the toolbox options in thetoolbox. As shown in FIG. 7, in this specific implementation, thetoolbox includes five options including a make suggestion option 730 a,a translate it option 730 b, a hear it option 730 c, a copy option 730d, and a quote option 730 e. The toolbox includes a user-clickableobject 735 (e.g., icon, link, or button) that when clicked or selectedcloses the toolbox and exits the toolbox program.

In a specific implementation, the system determines which toolboxoptions a user is authorized to perform and shows those options. Toolboxoptions that the user is not authorized to perform are not shown. Forexample, the system may allow only registered uses to make suggestions.If the user is a registered user the make suggestion option will beshown in the toolbox. If the user is not a registered user the makesuggestion option will not be shown in the toolbox.

Various features of the toolbox are also described in U.S. patentapplication Ser. No. 12/390,450, filed Feb. 21, 2009, which isincorporated by reference along with all other references cited in thisapplication.

In a step 620 (FIG. 6), the system receives a user selected toolboxoption. In a step 625, the system performs tasks associated with theselected toolbox option. In a specific implementation, one or more ofthe flow steps shown in FIG. 6 is performed using executable code. Thiscode can be executable source code, interpreted code, or compiled code(e.g., binary or machine code). This code can be executed by a browseror other execution mechanism (e.g., interpreter, compiler, plug-in, orbrowser plug-in) available on client device where the toolbox isinvoked. The code is executed by the processor of the client device.

The toolbox tool may be implemented using cloud computing, where usersaccess the tool through the cloud. The toolbox can be updated in thecloud, and delivered to users through, for example, their web browsers,so users do not need to manually update toolbox software on theirsystem. The code may be embedded with the content (e.g., document or Webpage) that is transmitted from the server to the client. For example,the code can be embedded in the Web page document. Whenever a user pullsup a Web page, the executable code is delivered to that user. In otherimplementations, the code may be sent or downloaded separately from theWeb page. For example, code can be downloaded as a plug-in that resideson the user's device, and the Web page invokes this plug-in.

Further, in a specific implementation, the code is written or uses AJAX(Asynchronous Java Script plus XML). One of skill in the art willrecognize that other techniques to create interactive Web applicationsmay instead or additionally be used. For example, some other languagesand protocols include Microsoft ActiveX, XML, PHP, Adobe Flash, Flex,Microsoft Silverlight, Java applets, JavaFX, Jscript, ASP,JavaServerFaces, Objective C, cascading style sheets (CSS), HTML5,H.264/AVC, Visual Basic for application, VBScript, Microsoft .NET, Lisp,Perl, Python, and others.

In a further implementation, the code for the toolbox resides at and isexecuted at server. The user will interact with the server in user theserver. In such an implementation, as more users use the toolbox, theserver handles serving the toolbox to these multiple users. Compared tothe above implementation where the code executes on the client,executing code on the client does not require as much resources of theserver; generally, such an implementation allows the system to scale tolarger numbers of users more easily.

Although we give some examples where there are two or three users inthis patent application. This is merely for illustration, because asystem of the invention can handle many numbers of users such as from afew (such as 4, 5, 6, 7-16, 30) to many numbers (such as 5000, 10,000,40,000, 1 million, 5 million, or more) at the same time. A system of theinvention allows these many users to use the toolbox to interact witheach other.

In a specific implementation, the executable code running on the clientdevice detects and the inputs of the user at the client device. Forexample, the user may indicate that the user wants to input somesuggested text at a particular position in a Web page (this same Webpage may include the executable code for the toolbox). The toolbox willthen draw a window on a screen of the client device seeking a suggestioninput from the user.

The user types in the user's suggestion and indicates completion byhitting enter or hitting an appropriately labeled button (e.g., acceptor finished) in the toolbox window. The user accepts the user's inputand stores this input. The toolbox can store this input temporarily atthe client device, such as for caching purposes, but the input will betransmitted to the server, where it is stored for later viewing byothers (e.g., another user at a different client device) who pull up theWeb page.

FIG. 8 shows a flow diagram for making suggestions to user createdcontent such as a body of text in a blog. An arrow 805 indicates theuser selected the make a suggestion option 730 a (FIG. 7).

In a step 810 the system displays a suggestion view of the toolbox. Thesuggestion view includes the selected content from the Web page, andsuggestion and explanation input boxes.

FIG. 9 shows an example of a suggestion view 905 of the toolbox. Thesuggestion view includes selected content 705 (FIG. 7) displayed in aselected content box 909, a Web page author (or author of the contentbox) 910, a suggestion input box 915, an explanation input box 920, anda submit button 925.

The selected content when displayed in selected content box 909 can bedisplayed using any color to help call attention to the selectedcontent. In a specific implementation, the selected content is displayedin red, but can be displayed in any color such as blue, yellow, green,orange, black, pink, and purple.

As shown in FIG. 9 a layout of the suggestion view includes the Web pageauthor in an upper left-hand corner of the layout and the selectedcontent in an upper right-hand corner of the layout. The suggestioninput box is below the Web page author and the selected content. Theexplanation input box is below the suggestion input box. The submitbutton is below the explanation input box. In other words, thesuggestion and explanation input boxes are between the Web page contentauthor or the selected content and the submit button. The explanationinput box is between the suggestion input box and the submit button.

However, it should be appreciated that FIG. 9 shows but one example ofthe layout or arrangement of the components (i.e., Web page contentauthor, selected content, suggestion input box, explanation input box,and submit button). The components can be arranged in any order orposition. For example, the arrangement of the Web page content authorand the selected content may be swapped. The selected content may bedisplayed in the upper left-hand corner of the toolbox. The Web pagecontent author may be displayed in the upper right-hand corner of thetoolbox, and so forth.

In a specific implementation, the selected content is also displayed inthe suggestion input box. That is, the suggestion input box defaults oris prepopulated with the selected content. The user can make thesuggestion by editing or changing specific portions of the selectedcontent without having to retype other portions of the selected contentthat the user wishes to keep. In another implementation, the suggestioninput box is blank or empty.

Generally, the suggestion input box requires input and the explanationinput box is optional. After the user clicks the submit button, thesystem checks whether or not the suggestion input box includes asuggestion. This check may be done at the client, at the server, orboth. If there is no suggestion the system prompts the user via a dialogbox to input a suggestion.

Referring now to FIG. 8, in a step 815 the system accepts the input fromthe suggestion and explanation input boxes.

In a step 820 the system associates the suggestion with the paragraph(i.e., paragraph identifier) that the selected content is in and theposition of the selected content within the paragraph.

In a step 825 the system stores the suggestion, explanation, paragraphidentifier, and position of the selected content in the suggestionsdatabase. The system makes an entry in the suggestions database thatincludes the suggestion identifier, suggestion, explanation, paragraphidentifier, and position. See FIG. 5. The entry may further includeassigning a status to the suggestion (e.g., assigning a new status).

In a step 830 the system updates the suggestions identificationdatabase. The system makes an entry in the suggestions identificationdatabase that includes the suggestion identifier, the suggesteridentifier, and the node identifier. See FIG. 5.

In a specific implementation, a link to view suggestions is displayed onthe Web page when the user created content includes one or moresuggestions.

In a specific implementation, the suggester can edit the suggestionafter the suggestion is submitted. For example, the suggester may editthe suggestion before it is approved or rejected. Generally, the user orsuggester is not allowed to delete a suggestion after it has been made.However, in other implementations a user can delete a suggestion afterit has been made.

FIG. 10 shows a flow diagram for approving and rejecting suggestions. Ina step 1005 one or more suggestions from the suggestions database isdisplayed on a Web page.

In a step 1015 the system receives an approval or a rejection of thesuggestion. In a step 1020, if the system receives a rejection of thesuggestion, the system changes the suggestion status from new torejected. In a step 1025 the system updates the suggestions historydatabase. See FIG. 5.

In a step 1030, if the system receives an approval of the suggestion,the system updates the Web page by replacing the selected content in theWeb page with the suggestion. In a specific implementation, the bodycolumn (see table B) is updated with the suggested text. In thisspecific implementation, the timestamp column (see table B) is likewiseupdated to indicate the date and time of the update.

In a step 1035 the updated Web page is stored in the user Web pagesdatabase. The browser window or Web page in the browser is refreshed toshow the new Web page with the selected content now replaced with thesuggestion.

In a step 1040, the system changes the suggestion status from new toapproved. In step 1025, the suggestions history database is updated.

Table L below shows an example of code for replacing the selectedcontent with the suggestion. This example of code is written in ascripting language that may be referred to as Personal Home Page (PHP).In a specific implementation, the selected content includes text from ablog. The code is executed when the user confirms their desire toreplace the selected content with the suggestion (e.g., user clicks a“yes, I'm sure” button). In other words, in a specific implementation,the system after receiving an indication of acceptance of a suggestionand before replacing the selected content with the suggestion, promptsthe user for confirmation (e.g., displays a dialog box requestingconfirmation). If the user confirms the acceptance, the selected contentis replaced with the suggestion. If the user does not confirm theacceptance, the selected content is not replaced with the suggestion.

TABLE L for($i = 0; $i < count($OrgArray); $i++) {  $block =ectoolbox_block_text($OrgArray[$i]);// here we block the Tags likeObject, Param, embed, table etc.,  if($block > 1)  $flag = 1;  if($flag== 0) {  if(trim($OrgArray[$i]) != ““) {     if($Sugg_Parent_ID ==$para) {     $WordArray = explode(“ “,$OrgArray[$i]);     $sugg_orginal= explode(“ “,$Sugg_Org_Cont);     $intersect =array_intersect($WordArray,$sugg_orginal);     $word_count = 1;    $flag = 0;     if(count($intersect) > 0 && isset($intersect) &&!empty($intersect)) {     for($j = 0; $j < count($WordArray); $j++) {    if($flag == 1) {     $WordArray[$j] = “!@#$%{circumflex over( )}&*(Temp_Variable_)(*&{circumflex over ( )}%$#@!”;//Here replace therest of the text with temp text     }     if($flag == 2) {     break;    }     if($word_count == $Sugg_Content1[0][“start_position_count”]) {    $WordArray[$j] = $Suggestion; // here push the suggested text to thefirst word of the original text $flag = 1;     }     if($word_count ==$Sugg_Content1[0][“end_position_count”]) {     $flag = 2;     }$word_count = $word_count + 1;     } $OrgArray[$i] = implode(““,$WordArray); } $new_word_array = array( );     $wc = 0; for($j = 0; $j< count($WordArray); $j++) { if($WordArray[$j] != “!@#$%{circumflex over( )}&*(Temp_Variable_)(*&{circumflex over ( )}%$#@!”) {$new_word_array[$wc] = $WordArray[$j]; // here remove the temp text    $wc = $wc + 1;     }     }  $OrgArray[$i] = implode(““,$new_word_array);     }     $para = $para + 1;     }  $un_block =ectoolbox_un_block_text($OrgArray[$i]); // here we unblock the Tags likeObject, Param, embed, table etc., if($un_block > 1)     $flag = 0;     }$ReplacedText = implode(“\n”,$OrgArray);//implode all array values andstore into a single variable

In a specific implementation, a suggestion status is one of five statustypes including new, approved, discarded, agreed to, and agree pending.The new status type is assigned to a newly submitted suggestion. Asuggestion with a new status type has not been approved or discarded. Inthis specific implementation, suggestions that are new are displayedwith an asterisk (e.g., orange asterisk) on certain Web pages such asthe suggestions summary page. This helps to focus the user's attentionon new or recent suggestions.

In a specific implementation, a suggestions summary page includes afirst tab page and a second tab page. The first tab page includes a listof suggestions given, identifies or displays the user who received thesuggestion, identifies the title of the document or blog post to whichthe suggestion was made, identifies the date, time, or both of when thesuggestion receiver viewed the suggestion, the status of the suggestion(e.g., discarded, approval pending, accepted, rejected, agreed, notagreed, conditionally accepted, conditionally rejected, and so forth), anumber of suggestions given, a number of suggestions approved, and anapproval rate.

The second tab page includes a list of suggestions received and mayinclude information that is similar to the first tab page. For example,the second tab page with the list of suggestions received may identifyor display the user who made the suggestion, the title of the documentor blog post to which the suggestion was made, the date and time of whenthe suggestion was viewed, the status of the suggestion, a number ofsuggestions received, a number of suggestions approved, and an approvalrate. The suggestions summary page can be filtered, sorted, andsearched. Suggestions may be filtered using any of the database fields(e.g., see table A) discussed in this application. Suggestions may befiltered based on user (or suggester), suggestion status, time ofsuggestion, date of suggestion, and so forth. Sorting suggestionsinclude sorting suggestions chronologically, reverse chronologically,and alphabetically. Sorting may be on multiple levels on multiple fields(e.g., sort on user first, then sort by date).

For example, the content owner may wish to see suggestions from aparticular user and ignore or hide suggestions from other users.Suggestions may be filtered by user (or suggester), date suggestion wasmade, time the suggestion was made, length of a suggestion, whether ornot the suggestion includes an explanation, language fluency of thesuggester, suggester's native country, suggester's rating information,one or more key words in a suggestion, explanation or both, suggestionstatus, or combinations of these—just to name a few examples.

The content owner may filter the suggestions to see suggestions from aparticular user, or users who have a certain rating or experience level,or members of a particular group (e.g., teachers or instructors, boardmembers, managers, students, a particular distribution list, or peers),while those users that are not part of that group will not be shown inthe summary screen.

The content owner may filter and view in the summary only suggestionswith respect to one paragraph of a page, while ignoring othersuggestions on the page. The content owner may filter and view in thesummary only suggestions after a particular date, while ignoring othersuggestions made before that date. The content owner may filter and viewin the summary only suggestions before a particular date, while ignoringother suggestions made after that date. The content owner may filter andview in the summary only suggestions after a time on a particular date,while ignoring other suggestions made before that time and date. Thecontent owner may filter and view in the summary only suggestions beforea particular time on a date, while ignoring other suggestions made afterthat time and date.

In a specific implementation, the system or a toolbox includes a searchtool to allow the user to search the suggestions. Search options includesearching based on key words, searches based on exclusions, searchesbased on exact phrases, searches based on any word in a phrase, searchescovering a specific paragraph, a specific grouping of paragraphs,documents, or both, and so forth.

The approved status type is assigned to the suggestion when the authorof the content approves the suggestion. The discarded status type isassigned when the author of the content rejects or discards thesuggestion.

In this specific implementation the status types agreed to and agreepending are used in cases where there are two or more suggestions forthe same selected content. For example, a first user may have made afirst suggestion to a selected content. A second user may have made asecond suggestion to the selected content. Initially, the status typefor the first and second suggestions is new. The content author can thenreview the first and second suggestions and decide, for example, whichsuggestion to approve. When the content author approves one of thesuggestions the status of the other suggestion changes from new to agreepending.

For example, if the content author approves the first suggestion thefirst suggestion changes from new to approved. The second suggestionchanges from new to agree pending. If the content author agrees with thesecond suggestion the status changes from agree pending to agree to. Ifthe content author disagrees with the second suggestion the statuschanges from agree pending to discarded.

In this specific implementation, the system will not replace theselected content (now having been replaced by the first suggestion) withthe second suggestion when the second suggestion is agreed to. Instead,the status agree to is used to indicate, for example, that while thecontent author generally agreed with the second suggestion, the contentauthor preferred the first suggestion. In another implementation,agreeing to the second suggestion replaces the selected content (orfirst suggestion). For example, the content author, after approving thefirst suggestion, may later prefer instead the second suggestion. Thecontent author can then accept the second suggestion and the system willreplace the selected content (or first suggestion) with the secondsuggestion.

In a specific implementation, a user is able to undo a suggestion. Forexample, after a suggestion has been approved and the suggestion hasreplaced a portion of the user created content, the user can undo asuggestion to arrive or revert back at the original content.

FIG. 11 shows an example of a Web page 1105 displayed within a browser1110. The Web page includes user created content 1115. In this example,the user created content includes one or more suggestions. In a specificimplementation, if there are current suggestions (e.g., new orsuggestions that have not been approved or rejected) a currentsuggestions link 1120 is displayed on the Web page adjacent to the usercreated content. If there are no current suggestions link 1120 is notdisplayed.

In this specific implementation, if there are old suggestions (e.g.,suggestions that have been approved or rejected) a suggestions historylink 1125 is displayed on the Web page adjacent to the user createdcontent. If there are no old suggestions link 1125 is not displayed.

FIG. 12 shows an example of a Web page 1205 to view and approve orreject (e.g., discard) suggestions when the user clicks suggestions link1120 (FIG. 11). A review view of a toolbox 1207 is invoked and drawn onthe page. First and second highlights 1208 and 1209 highlight selectedportions of the user created content for which there are suggestions. Inthis example, two suggestions have been made. A first suggestion hasbeen made to a first selected content 1231. The first selected contentis highlighted by the first highlight. A second suggestion has been madeto a second selected content 1232. The second selected content ishighlighted by the second highlight.

Table M below shows an example of code for highlighting portions of theuser created content for which there are suggestions.

TABLE M for(i=0;i<sid_array.length;i++) { var parent_num = pid_array[i];   var id_s = “Sub_Id_”+sid_array[i]+”_Ec_Tool_Box”;    varstarting_point =parseInt(each_count_start[parent_num])+parseInt(start_position[i])−2;   var ending_point =parseInt(each_count_start[parent_num])+parseInt(end_position[i])−2;   if(parseInt(start_position[i])==1) {       var para_first = newArray( );       para_first = whole_content[starting_point].split(“>“);      para_first[1] = “<span class=‘Sugg_Content_dotted’id=‘“+id_s+”‘onclick=‘Show_Suggession(\”\”,\”\”,\”“+sid_array[i]+”\”,\”\”);’>“+para_first[1];       var first_content =para_first.join(“>“);       whole_content[starting_point] =first_content;    } else { whole_content[starting_point] = “<spanclass=‘Sugg_Content_dotted’id=‘“+id_s+”‘onclick=‘Show_Suggession(\”\”,\”\”,\”“+sid_array[i]+”\”,\”\”);’>“+whole_content[starting_point]    }   if((each_count_end[parent_num] − 2) == ending_point)  {      para_last   = whole_content[ending_point].split(“</”);      para_last[para_last.length−2] =para_last[para_last.length−2]+”</span><span id=‘pos_”+sid_array[i]+”‘style=‘visibility:hidden’>&nbsp;</span>“;       last_content =para_last.join(“</”);       whole_content[ending_point] = last_content;   } else {       whole_content[ending_point] =whole_content[ending_point]+”</span><span id=‘pos_”+sid_array[i]+”‘style=‘visibility:hidden’>&nbsp;</span>“;    }    }

In a specific implementation, the toolbox is drawn in a floating windowand can be repositioned by the user. In another implementation, thetoolbox is drawn in a fixed or non-floating window.

This toolbox includes a content author box 1225, a selected content box1230, a suggester box 1235, a suggestion box 1240 with an editsuggestion link 1242, an explanation box 1245, an approve button 1250, adiscard button 1255, a previous button 1260, and a next button 1265. Asexplained, in a specific implementation, a user can submit a suggestionwithout having to input an explanation for the suggestion. If this isthe case explanation box 1245 is not be displayed since there is noexplanation to display.

In a specific implementation, the toolbox has a layout as shown in theexample of FIG. 12. A first or top row of the layout includes thecontent author box and the selected content box. A second row includesthe suggestion box. A third row includes the explanation box for thesuggestion, if any. The suggester box spans across the second and thirdrows. A fourth row includes the approve and discard buttons. A fifth rowincludes the previous and next buttons.

However, it should be appreciated that FIG. 12 shows but one example ofthe layout or arrangement of the components. The components can bearranged in any order or position.

The content author is the user who authored the user created content. Ina specific implementation, the toolbox shows one suggestion and theassociated selected content and explanation at a time. Thus, in thisexample, the selected content box displays either first selected content1231 or second selected content 1232. Similarly, the suggestion boxdisplays either the first suggestion or the second suggestion. The nextand previous buttons allow the user to scroll though the varioussuggestions that might have been made to various portions of the usercreated content. However, it should be appreciated that the toolbox maydisplay any number of suggestions and selected content.

Typically, the order in which the suggestions are traversed using thetoolbox is with respect to the position or location of the suggestionswithin the user created content. In a specific implementation, the orderis left to right and top to bottom within the user created content. Asan example, a location of first selected content 1231 is above alocation of second selected content 1232 within user created content1115. Thus, selected content box 1230 will display the first selectedcontent and suggestion box 1240 will display the first suggestion, i.e.,the suggestion associated with the first selected content.

In various other implementations, the order in which the suggestions aretraversed is right to left and bottom to top with respect to theposition or location of the suggestions within the user created content.The suggestions are ordered according to the time they were made (e.g.,chronologically or reverse chronologically).

In a specific implementation, a highlighting style of the highlights isbased on which suggestion is currently displayed in the toolbox. Thisallows the user to quickly associate the suggestion displayed in thetoolbox with the specific piece of selected content within the usercreated content. When displaying the first suggestion in selectedcontent box 1230 first highlight 1208 is displayed using a firsthighlighting style. Second highlight 1209 is displayed using a secondhighlighting style, different from the first highlighting style.

In this specific implementation, the first highlighting style includes asolid underline. The second highlighting style includes a dotted ordashed underline. It should be appreciated that any highlighting styleor any mark or visual indicator may be used. Some examples of otherhighlighting styles or techniques include colors, boxes, clouds,bubbles, shading, icons, animation, different font types, different fontsizes, and combinations of these (e.g., solid red underline or dashedred underline).

When the user clicks the next button to advance to the second suggestionthe highlighting style of first highlight 1208 changes from the firsthighlighting style to the second highlighting style. The highlightingstyle of second highlight 1209 changes from the second highlightingstyle to the first highlighting style.

The content author, after reviewing the suggestion and explanation, ifany, can approve the suggestion by clicking the approve button or rejectthe suggestion by clicking the discard button.

Edit suggestion link 1242 allows the content author to edit thesuggestion before approving or discarding the suggestion. For example,the content author, after reviewing the suggestion, may generally agreewith the suggestion, but may want to make some changes to thesuggestion. The content author can click the edit suggestion link to bepresented with an editable version of the suggestion. The content authorcan then edit the suggestion. When the content author clicks the approvebutton, the edited suggestion replaces the selected content.

In a specific implementation, the system or a toolbox includes one ormore filters to allow a user to filter suggestions. For example, a userA may wish to see suggestions from a particular user and hidesuggestions from other users. The particular user may be, for example,someone that user A particularly trusts to offer good suggestions. Anyof the database fields discussed in this application, includingcombinations of database fields, may be used to filter suggestions.

Suggestions may be filtered by user (or suggester), date suggestion wasmade, time the suggestion was made, length of a suggestion, whether ornot the suggestion includes an explanation, language fluency of thesuggester, suggester's native country, suggester's rating information,one or more key words in a suggestion, explanation or both (e.g., showme suggestions that have the word “lobster” in them), suggestion status,or combinations of these—just to name a few examples.

User A may filter the suggestions to see suggestions from users who havea certain rating or experience level. For example, user A may filter thesuggestions to see suggestions from users who have made a certain numberof suggestions (e.g., show me suggestions from users who have made 50 ormore suggestions), user A may filter the suggestions to see suggestionsfrom users who have a certain approval or acceptance rating (e.g., showme suggestions from users who have had at least 80 percent of theirsuggestions accepted, show me suggestions from users whose suggestions Ihave previously accepted), user A may filter the suggestions to seesuggestions from their network of friends (e.g., show me suggestionsfrom users who are in my friends group, show me suggestions from userswho are in my family group), user A may filter suggestions to seesuggestions from suggesters who have a particular language fluency(e.g., show me suggestions from users who are experts in Japanese, showme suggestions from users who are fluent in Spanish), and so forth.

These filters can help user A to sort through suggestions, especiallywhen the document includes dozens, hundreds, or thousands ofsuggestions.

In a specific implementation, the system or a toolbox includes a searchtool to allow the user to search the suggestions. Search options includesearching based on key words, searches based on exclusions (e.g., searchsuggestions having the word “rock” but not the word “olive”), searchesbased on exact phrases, searches based on any word in a phrase, searchescovering a specific paragraph, a specific grouping of paragraphs,documents, or both, and so forth.

Referring now to FIG. 7, toolbox 725 may instead or additionally includeany of the other options besides make a suggestion 730 a for the user toselect. For example, the user after selecting content 705 may translatethe selected content by clicking the translate it option.

In a specific implementation, the “translate it” feature is initiatedwhen the EnglishCafe user wants to read the text of the blog translatedinto some other language. It may be done by selecting the text for whichthe user wants to translate and selecting the translate it option fromthe toolbox. In another implementation, the user can enter a suggestionin one particular language (e.g., Spanish) and have it translated intoanother language (e.g., English). Other translations may be Chinese toEnglish, English to Chinese, English to German, German to English,English to Spanish, and Spanish to English, Spanish to Hindi, and Hindito English, and others. The user can view the translated suggestion andmake edits to the selected translation before indicating or electing toenter and save the suggestion.

In a specific implementation, the user who would like to read a text inthe desired language can be an EnglishCafe user, authenticated user oran anonymous user. An example of the flow of the translate it feature isas follows.

1. The user visits a blog post.

2. The user wants to translate a part of text of the blog post to someother language for reading.

3. The user selects the part of text to be translated, when a pop-upwindow of toolbox opens up.

4. By selecting the “translate it” option, another window opens up.

5. The selected text from the blog will be highlighted in red in the“selected text” textbox. Beneath that are the “translate selected text”label and the “English to” dropdown box which lists all the pre-definedlanguages.

6. The user selects a language from the dropdown. The translated textfrom English to the selected language is shown beneath the dropdown boxwith the label “translated text.”

Table N below shows an example of code for translating the selectedcontent.

TABLE N $url =‘http://releasecorp.globalenglish.com/englishcafe/ecapi.asp?mode=trans&language=‘.$lang.’&word=‘.$str.”&ecid=“.$user_id.”&key=“.$encrypt_key;    // here we areusing CURL to fetch the data from another server    using URL. $ch =curl_init( );    curl_setopt($ch, CURLOPT_HEADER, 0);    curl_setopt($ch, CURLOPT_REFERER, $url);    curl_setopt($ch, CURLOPT_URL, $url);   curl_setopt($ch, CURLOPT_POST, 1);    curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);    curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);    $data = curl_exec($ch); The above code will give the XMLOutput only. From our end we will parse that XML. This is the main partof server side code (PHP) to Parse XML. $this->resParser =xml_parser_create ( ); xml_set_object($this->resParser,$this);xml_set_element_handler($this->resParser, “tagOpen”, “tagClosed”);xml_set_character_data_handler($this->resParser, “tagData”);$this->strXmlData = xml_parse($this->resParser,$strInputXML );if(!$this->strXmlData) { die(sprintf(“Sorry, There is a problem with ourTranslation”)); //die(sprintf(“XML error: %s at line %d”,xml_error_string(xml_get_error_code($this->resParser)),xml_get_current_line_number($this->resParser))); }xml_parser_free($this->resParser);

Aspects of a translation feature are also described in U.S. Pat. No.7,389,221, issued Jun. 17, 2008, which is incorporated by referencealong with all other references cited in this application.

The user after selecting content 705 may hear a vocalization of theselected content by clicking the hear it option.

In a specific implementation, the “hear it” feature is initiated whenthe EC user wants to hear the text of the blog. It may be done byselecting the text for which the user wants to hear and select the hearit option from the toolbox. In a specific implementation, the user whowould like to hear a text can be an EnglishCafe user, authenticateduser, or an anonymous user. Audio drive should be installed. A flowexample of the hear it feature is as follows.

1. The user visits a blog post.

2. The user wants hear a part of text of the blog.

3. The user selects a part of text of the blog when a pop-up window oftoolbox opens up.

4. By selecting the option “hear it,” another window opens up.

5. The selected text from the blog will be highlighted in red in the“selected text” textbox. Beneath that are the “hear selected text”label, “choose voice” dropdown box which lists all the pre-definedvoices and the “select speed” option buttons for normal or slow speed.

6. The user selects a desired voice from the dropdown, selects the speedand clicks the play button.

7. The user hears the desired text in the desired voice.

Table O below shows an example of code for obtaining an audio file(e.g., .wav file) of the selected content.

TABLE O $wave_file =“http://releasecorp.globalenglish.com/englishcafe/ecapi.asp?mode=tts&voice=“.$voice.”&speed=“.$speed.”&word=“.$str.”&ecid=“.$user_id.”&key=“.$encrypt_key;

The user after selecting content 705 may copy the selected content to aclipboard by clicking the copy option.

In a specific implementation, the “copy it” feature is initiated whenthe EC user wants to copy a portion of the text of the blog. It may bedone by selecting the text for which the user wants to copy and selectthe copy option from the toolbox. In a specific implementation, the userwho would like to copy a text is an EnglishCafe user, authenticated useror an anonymous user. An example flow of the copy feature is as follows.

1. The user visits a blog post.

FIG. 13 shows an example of a Web page 1305 where multiple suggestions(i.e., two or more suggestions) have been made to the same selectedcontent. In this example, first and second suggestions 1310 and 1315,respectively, have been made to a selected content 1320. The systemallows any number of suggestions to be made to a selected content. Forexample, there can be two, three, four, five, six, seven, eight, nine,ten, or more than ten suggestions made to the selected content.

Thus, in a specific implementation, the system allows suggester A toselect a portion of content (i.e., selected content 1320) and make thefirst suggestion. The system allows suggester B to select the sameportion of content (i.e., selected content 1320) and make the secondsuggestion. If the suggester so desires the suggester can provide anexplanation of the suggestion.

A user can use the next and previous buttons of the toolbox to scrollthrough and view the first and second suggestions. For example, in thisspecific implementation, selected content 1320 is displayed in selectedcontent box 1230 and the first suggestion is displayed in suggestion box1240. The user can click the next button to view the second suggestion.That is, the toolbox then displays the second suggestion in suggestionbox 1240. Selected content 1320 will continue to be displayed inselected content box 1230.

Thus, the user, such as the content author can view the differentsuggestions that have been made to the selected content. The contentauthor can choose which suggestion (e.g., first or second suggestion) toapprove. For example, the selected content may state:

“The motor vehicle propelled itself up the cliff and landed in nature'swatery bosom.”

Suggester A can offer as the first suggestion:

“The car sped up the cliff and plummeted into the ocean.” And offer theexplanation that the original sentence was awkward and bloated.

Suggester B can offer as the second suggestion:

“The car threw itself off the cliff.”

The content author can then review the two suggestions and decide whichsuggestion to approve. For example, the content author may decide thatthe first suggestion is more appropriate and approve the firstsuggestion. Then, the selected content will be replaced by the firstsuggestion.

Furthermore, a suggester can make any number of suggestions for aselected content. For example, the system allows suggester A to make thefirst suggestion for the selected content. After making the suggestion,suggester A may think of another alternative suggestion. Thus, thesystem allows suggester A to once again select the content (i.e.,selected content) and make the second suggestion.

A selected content can overlap or partially overlap with anotherselected content. For example, a portion of the first selected contentmay also be in the second selected content. The portion may be referredto as the overlapping portion. A first suggestion is associated with thefirst selected content. A second suggestion is associated with thesecond selected content. In a specific implementation, when the contentauthor approves the first suggestion the first selected content isreplaced with the first suggestion. In this specific implementation, thesystem blocks the content author from approving the second suggestionsince the second suggestion may no longer be relevant. That is, thefirst selected content which includes the overlapping portion has beenreplaced with the first suggestion. And, since the second suggestion wasmade in reference to the overlapping portion, the second suggestion mayno longer be relevant.

In another implementation, the system allows the content author toapprove the second suggestion after the first suggestion has beenapproved. In this specific implementation, the approval of the firstsuggestion is undone. That is, the first suggestion is replaced by thefirst selected content. The second selected content is then replaced bythe second suggestion.

The system facilitates or permits any number of annotations (e.g.,suggestions or comments) to be associated or attached to user-generatedcontent. These annotations can be by the same user or different users.So, a first user can select and annotate an entire paragraph. Then afterthe first user's annotation, a second user can select and annotate anyportion of that paragraph (or the entire paragraph again) withoutrestriction. The second user's annotation will not be a subannotation orreply to the first user's annotation. This feature of the system helpsprevent system misuse (e.g., spam users) or others who might want tovandalize another person's user content.

Without this feature of the system, a first user may vandalize anotherperson's user content (e.g., a fan site for the San Francisco Giants) byselecting the entire content and leaving a note “The Dodgers Rule!” Thenwithout the implementation of described in this application, furtherannotations would be prevented altogether (but other users will see thegraffiti). Or if the system allows subannotations or replies to thefirst annotation, then other user will see the graffiti first beforeother perhaps more serious comments. Therefore, the implementation asdescribed in this application facilitates an open system which does notpermit those who intend to misuse the system from abusing other user'scontent.

Further, the system facilitates the sharing of ideas such as forlanguage learning and does not give any preference to the first user wholeaves a comment. Subsequent users can leave annotations just as if theywere the first user to leave an annotation. Later users who leavecomments are not prevented from commenting on exactly the same usercontent or any portion of user content which was previously commentedon.

In some implementations, users may be blocked from making suggestions.For example, users who abuse the system by making inappropriatesuggestions (e.g., suggestions having foul language, racial epithets, orabusive language) may be blocked from making suggestions. The system mayinclude a link to report users who make inappropriate suggestions.

In some implementations, users may be blocked from receivingsuggestions. In a specific implementation, the system includes a paymentscheme based on the suggestions. For example, in variousimplementations, a user is permitted to receive and access a thresholdnumber of suggestions without having to make a payment to the system.Once the threshold number is reached, the user must make a payment inorder receive and access suggestions. A user may be permitted to receiveand access an unlimited number of suggestions for a threshold timeperiod, such as during a trial time period. Once the trial time periodhas elapsed, the user must make a payment in order to receive and accesssuggestions.

A user may be permitted to receive a suggestion (or receive anindication that a suggestion has been made), but may not be permitted toaccess the suggestion (e.g., view the suggestion) unless the user makesa payment. The payment scheme may include a subscription-based paymentmechanism, a pay-as-you-go payment mechanism, or both. In thesubscription-based payment mechanism, a user pays, for example, amonthly fee to receive and access suggestions. The number of suggestionsallowed to be received and accessed may be unlimited or may be capped ata specific threshold and thereafter an additional charge may apply. Inthe pay-as-you-go payment mechanism, the user pays to receive and accesssuggestions on a per suggestion basis.

In another implementation, an advertisement is included with thesuggestion and a user must view the advertisement, listen to theadvertisement, or both before being permitted to view the suggestion. Inanother implementation, a user can make a payment to not have to viewthe advertisement, listen to the advertisement, or both before beingpermitted to view the suggestion.
